That's it as the game finishes in a 1-1 stalemate that was just about right. It wasn't a classic as both sides edge that little bit closer to Premier League safety.
Bardsley loops a free-kick into the Southampton box from deep but Hooiveld is again in the right place to head clear.
Hooiveld gets in a decent defensive header as Johnson fires one into the Southampton box.
There will be a minimum of three minutes stoppage time.
Southampton very much in the ascendancy as Sunderland find themselves on the back foot. Rodriguez thought he'd muscled his way through but was pulled back for a nudge on Rose.
What a save by Mignolet to deny Lambert at the death. From Rodriguez's flick-on Lambert took the ball on his chest before firing a low angled effort that was brilliantly repelled by Mignolet.
Tension envelops both sets of supporters as a nervy atmosphere lingers in the air. It's all gone a little scrappy.
Waste by Southampton as Lambert is lazily caught off-side from Ward-Prowse's cross.
Davis winds one up on the edge of the area but N'Diaye, who's had a fair game for Sunderland, gets in a decent block.
Tension rising as the seconds tick away at the Stadium of Light. It could go either way, with both sides looking as though they want to get the job done today with a three-point haul.
Rose has kept going all afternoon for Sunderland but his cross is blocked as Southampton bid to keep hold of what would be a decent point.
A good run by Shaw as Southampton turn the screw having levelled ends with Sunderland clearing for a throw. Puncheon's goal has deflated the home crowd.
Southampton's leveller was all about the substitutes. Ward-Prowse's cross found Puncheon and from his excellent header Mignolet produced an even better save. Unfortunately for the Sunderland 'keeper the ball fell to the feet of the Southampton man, who made no mistake from close range.
GOAL for Southampton!!! Puncheon fires in at the second attempt to level. Super-sub.
Sunderland make their second change as Vaughan comes on for Larsson. That's his 18th substitute appearance of the season.
Double change for Southampton. Ward-Prowse and Puncheon for Cork and Lallana.
Southampton striker Rodriguez booked for what looks to be dissent.
It's all Sunderland as Bardsley fires in another strike from range. It causes consternation in the box but is eventually cleared.
Only Bardsley's second goal in two years but it was a beauty. Johnson's little pass played in the bombarding full-back down the right and from the angle he scorched in a pearl of an effort, albeit one that took a slight deflection off Hooiveld.
GOAL for Sunderland!!!! Screamer from Phil Bardsley. An absolute arrow from the full-back that takes a nick off Hooiveld.
Johnson needlessly concedes a free-kick when all he needed to do was pin Shaw in the corner. He's been pretty poor today the Sunderland winger.
Bit of a lull here but at least Sunderland are getting closer to Graham and trying to squeeze higher up the pitch. Southampton have struggled to play any real football this half.
Bardsley whips in a delivish cross on the overlap but it's a touch too hard and flashes past everyone in the box. Better again from Sunderland though.
Better from Sunderland as Rose looks to get in again but his cross is poor and goes behind for a corner. The majority of the 42,000 present are in good voice whenever Sunderland give them something to get excited about.
Boruc steps off his line to take Larsson's corner all too easily.
Sunderland win a corner off Clyne. Much better tempo to the second period. Still think one goal would be enough to win it though.
From a Southampton corner Rodriguez meets Davis' cross with a decent header but Mignolet saves easily enough. The big man looks a threat in the air though when he's given decent service.
Good change of pace needed from Cuellar as beats Rodriguez in a foot race to put the ball behind for a corner.
Home crowd not happy as Larsson punts one forward into no man's land when Graham wanted the ball to his feet. Di Canio not impressed either.
Clumsy challenge on Lallana by Wickham gives Southampton a free-kick down the right flank. Davis' set-piece is dreadful and easily cleared.
Game comes to life as Sunderland sweep up field to play in Rose down the left. The full-back's cross was decent but Graham's wild swipe when well placed fails to make any kind of contact. Decent chance for the Black Cats.
Southampton win a corner as Lallana's snapshot is blocked by O'Shea. From the set-piece Mignolet is forced into a smart low stop as he pushes away Rodriguez's header.
Wickham hasn't got much change out of Southampton's defenders so far but he's given them something to think about. He's a big lad and he's keen to throw his weight around by the look of it. Game needs an injection of passion that's for sure.
Sunderland look to be pressing more, there's certainly a better intensity to their game. I suspect a number of their players took to the field with a Di Canio sized flea in their ear...
Excellent again by Luke Shaw down the left as he skips past Bardsley but Mignolet is on hand to take his cross comfortably.
Second half gets underway with Sunderland adding Wickham to their attack to support Graham. Decent call by Di Canio as Sunderland lacked any kind of punch in the first period.
Conor Wickham on for McClean.
That's your lot. It's been pretty dire in truth, with neither goalkeeper having been unduly pressured. A point apiece should be enough to keep both sides up and it looks as though neither manager has set his side up to get much more than that.
Davis gets in an excellent block on the edge of Southampton's box to deny Larsson, whose shot from range looked to have real purchase.
Half is drawing to a close at a snail's pace. The most interesting thing I can say about the game so far is that there's been an awful lot of throw-ins. I'll have to check the stats to see if a record has been set.
Decent opportunity for Lambert after he brilliantly brought the ball down from a chipped Davis pass with his head, only to miscue his shot straight at Mignolet when well placed.
Best chance of the half for Sunderland sees Johnson meekly prod for goal from O'Shea's nod down, to allow Boruc an easy save.
Decent run from Colback wins a corner for the home side off Jack Cork. He's been arguably Sunderland's best player so far. Whipped ball in from Johnson is initally cleared before the Black Cats winger sees a second delivery put behind for another corner.
Lallana pulls one a couple of yards wide after Rose's poor defensive header on the edge of Sunderland's box. The Southampton man has not been at his best but is at least trying to get in around and behind his strikers.
Yet again Lallana wastes a decent opportunity to deliver into the area from a set-piece. Maybe time to get Lambert's left peg on free-kicks and corners?
From the resulting corner Mignolet again showed assured handling as he took Lallana's cross into his chest. Southampton turning the screw but need more quality in their deliveries.
Best chance of the half sees Mignolet produce a decent stop to deny Rodriguez, with the rangy striker side footing through a crowd off a Lallana corner.
It's pretty desperate stuff from Sunderland so far. Johnson and McClean are showing little inclination to get close to Graham, which essentially is leaving a shy-of-confidence striker up against four Southampton defenders.
First effort on target sees Southampton striker Lambert force Mignolet into a comfortable save with a daisy-cutter from range.
Strong break from N'Diaye as he makes real strides before firing for a goal when a pass wide to McClean might have been the better option. Seconds earlier it was Colback who gave Sunderland's fans something to cheer as he produced a lung-busting challenge to thwart Shaw.
Clyne shanks one out of play under no pressure to end a decent Southampton move somewhat disappointingly. It's that kind of game.
Slightly better from Sunderland as Rose shows an inclination to bomb on. It's not a bad contest between him and Clyne. Attack ends though when McClean gets his pass all wrong as Southampton are gifted a throw.
Adam Johnson sums up his season (with the exception of Newcastle game) as he hits a free-kick way past Boruc's far post.
Excellent forward foray from Saints right-back Clyne as he makes real inroads before putting in a decent low cross that is cleared on the stretch by Cuellar. More of these type of exertions are needed to liven a fairly insipid contest so far.
Graham looks isolated for the home side. Southampton are all too easily playing it out from the back, with no pressure exerted on them when in possession. Way too deep.
Lallana set-piece causes a little consternation in Sunderland's backline but McClean is on hand to block Hooiveld's header.
It's still early days but if I had to put money on it I'd say this game isn't destined to be a classic. Plenty of endeavour but there's been a distinct lack of quality so far.
Southampton fans cry for Davis to shoot when well placed on the edge of the area but he chooses to tick things over by playing the ball wide and the chance is lost.
Best passage of play from Sunderland culminates in Rose's cross on the overplay being cleared by Clyne. It's still Southampton though looking the likelier.
Shaw again a good out ball for Southampton as he wins a throw off Bardsley deep in Sunderland's half. Looks as though Sunderland will be content to sit, soak and counter. Home fans in good voice as a chant for Di Canio reverberates around the ground.
Mignolet is pressured into giving a corner away from Danny Rose's short backpass. Sunderland's keeper is equal to it though as he fists the ball away from the area under pressure from Lambert.
Quick feet from N'Diaye wins Sunderland a free-kick on halfway. They've set their game plan out early as centre-halves are summoned forward. Fonte rises earliest to head away danger though.
Lallana overhits free-kick down the right with too much power as Lambert is unable to keep the ball in at the far post. A waste as it was in a dangerous position.
All of a bit listless from Sunderland so far. Cuellar has gone long a couple of times when patience would have been a better option. It's Southampton looking a little more composed.
First corner of the day comes to nothing. Southampton schemer Lallana looped in a hanging cross but Mignolet had no trouble plucking it out of the air.
Nice little pocket of play from Southampton, with Luke Shaw ever ready to get down the left flank. Attack fizzles out though.
All a bit scrappy so far, with both sides having squandered possession a little too readily in the opening sparring.
Sunderland get the game underway. Massive day for Danny Graham as he kicks-off desperate to get his first Sunderland goal.
Not long to go at the Stadium of Light, with John O'Shea and Adam Lallana in the tunnel ready to lead out their respective sides. The theme tune of The Apprentice is blaring out over the tannoy. Would be more apt perhaps if Martin O'Neill and Nigel Adkins were still in charge.
Chris Lye: Sunderland to be in wonderland after today, 2-1 to the mackems with qpr beating Newcastle 2-1.
Jame Cogle: Here we go! This is it for the black cats! Di Canio can do it now, looking for a win to keep us up.

Courtesy of our friends at Opta here's a couple of interesting match facts to impress/bore your friends with....
Southampton: Boruc, Clyne, Hooiveld, Fonte, Shaw, Steven Davis, Schneiderlin, Cork, Lallana, Rodriguez, Lambert. Subs: Kelvin Davis, Yoshida, Forren, Ward-Prowse, Mayuka, De Ridder, Puncheon.
Sunderland: Mignolet, Bardsley, O'Shea, Cuellar, Rose, Larsson, N'Diaye, Colback, McClean, Johnson, Graham. Subs: Westwood, Wickham, Kilgallon, Vaughan, Mangane, Marrs, Mandron.
The hosts head into the game at 16/1 to go down, a price which has drifted out from 6/4 thanks to picking up seven points from five games under Paolo Di Canio. Failure to win for Mauricio Pochettino's men, who sit a point ahead of their hosts, could see them dragged deep into trouble if the Latics beat Arsenal on Tuesday night, but they are currently 50/1 outsiders for the drop.
Welcome to our live minute-by-minute coverage of Sunderland's clash with Southampton from the Stadium of Light. According to our stat man a draw would be enough to secure both clubs their top flight status so here's hoping it's not going to be dead-rubber. With Paolo Di Canio on the touchline I suspect it won't. Full team news and betting tips to follow...
