Morrison unleashes a powerful effort, but the Italian saves well again.
Late flurry from West Brom perhaps? Mannone struggles to deal with Brunt's cross under pressure from Dawson.
On comes Giaccherini for Cattermole, to a standing ovation from the Stadium of Light faithful.
Giaccherini is set to replace Cattermole as the game wears on here. Both sides have seemingly settled for this.
Cattermole bursts forward amidst cries from the Sunderland fans to shoot. He does, but it's blocked.
Berahino comes off, replaced by Matej Vydra.
Slick football from Sunderland again. Borini plays in Vergini who bursts a gut to get their on the right-hand side, but his low shot creeps past the post.
What a chance that is! Borini does excellently to win the ball and play in Colback, whose cross just needs a touch from Altidore, but he manages to tap it wide of an open goal.
Sessegnon has been as lively a player as West Brom have had this evening. He wriggles his way into the area but drags his shot wide.
The aforementioned substitutions for Sunderland then. Bridcutt and Altidore replace Johnson and Wickham.
Berahino lets fire with a more than ambitious effort from an incredibly narrow angle, which Mannone predictably sees out.
Altidore and Bridcutt are preparing themselves on the touchline. Wickham and Johnson the likely substitutes.
45,181 is the attendance for tonight's match. Great turnout from both fans.
Berahino finds Dawson wide on the right, but somehow his cross doesn't find that vital touch, with Anichebe looking on.
Brunt hits a cross to the back post as West Brom continue to enjoy some more possession, but Mannone claims well.
Dorrans and Morrison combine effectively to play the ball into Anichebe's feet, but with his back to goal O'Shea is always in control, and the Irishman pokes the ball away.
Sessegnon breaks down the left and crosses to Anichebe, but he's crowded out and Sunderland clear.
Bit brighter from the visitors at the start of this half. Dawson floats over a cross that just evades Anichebe.
Craig Dawson and Youssouf Mulumbu replace Steven Reid and Claudio Yacob at half-time for the visitors.
Charlie Bowman (@bowmanator97) "looks like Sunderland are staying up. They've looked quite classy in the run in", and Ewan Brown (@ewanbrown229): "Cattermole is playing outstanding and safc will win 3-1" have had their say on Twitter.
Jack Forster is another revelling in Sunderland's seemingly inevitable great escape: "Couldnt be a better first half from safc, Great performance especially from catts and great play from the left side of Sunderland , Like to see wickham to get a goal but larrson been quite but second half should be better , another 4 -0 win for me."
Plenty of delighted Sunderland fans, too. Here's Layla Aitbenmoussa: "I can't believe how Sunderland have turned their season around. The mighty boys are doing us proud and it looks like we'll be enjoying premier league football again next season. I'm predicting 5-0."
Plenty of understandable praise for the Mackems from our readers. Lewis Dunn is first up: "What a half! I so wish sunderland could have started the season like this! It's took a while in coming but you can see the transformation under poyet. I can see it being another Cardiff...4-0 sunderland...borini with his second and Johnson to get one too!! FTM"

Great first-half from Sunderland - Cattermole and Borini in particular - while West Brom have looked flat. You can tell which side is in form and which is not, but luckily for West Brom, they're surely already safe.
Cattermole puts in a great challenge on Sessegnon as West Brom threaten to break. Man of the match so far.
Trickery from Johnson as he cuts inside with stepovers before laying off to Borini, but there's no power on the shot and Foster collects.
First shot on target for West Brom as they pour forward with Berahino, whose curling effort is well kept out by Mannone.
Berahino picks out Sessegnon wide on the right, and the Benin international cuts inside to shoot but it's well blocked.
A near-post corner is nearly tapped home by Wickham but it's blocked on the line.
Sunderland can smell blood here. Alonso is released again down the right-hand side and his cross to the back post is knocked behind for a corner.
Gorgeous football from Sunderland. Borini finds Larsson in the centre of the pitch and continues his run, before the Swede chips in a sublime ball which the Italian dispatches excellently.
STUNNING GOAL FROM BORINI. 2-0 SUNDERLAND!
Sloppiness from Yacob lets in Colback, but the versatile midfielder can't adjust his feet to release to Borini.
Colback finds Wickham on the angle of the 18-yard box, but the confident striker skies his effort.
Alonso's deep cross threatens to find Wickham, but it's headed out for a corner.
Johnson is played in down the left and breaks into the area, but his low cross is blocked by Reid.
Little to nothing in terms of an attacking threat from West Brom so far. Sunderland are in control at the minute.
Cattermole has been impressive so far, he's been everywhere. Morrison clips him on the halfway line and receives a speaking to.
Alonso does very well as he bursts down the right-hand side before his low cross reaches Colback, who does excellently to divert the ball past Foster.
GOAL! COLBACK TAPS IN THE OPENER.
Wickham does very well to get in a cross under pressure on the left, but no Sunderland players are there to tap home.
A free-kick from 35 yards out is crossed in by Larsson, but McAuley is on hand to head clear.
How that's not gone in is a mystery. The corner is whipped in and just needs a touch, a deflection to go in, but it narrowly evades everyone.
First real chance of the game and it's to the home side. Borini works into space and unleashes a powerful effort that's headed straight into the top corner, but Foster keeps it out with a great save.
Good work from Sessegnon as he bursts forward into Sunderland's area, but he's soon crowded out by three home players.
Evenly matched sides at the minute, both enjoying periods of possession.
Cattermole finds Johnson with an impressive 30 yard pass, but the winger's cross goes behind for a goal kick.
Sunderland start us off, kicking from left to right.
Just three minutes until kick-off now. Gordon Henshaw is next to air his views: "Used to so many ups & downs with SAFC but I cant see anythig less than a 3-1 home win tonight. Wickham x2 and Borini and then a consolation for WBA from Sessegnon. HAWAY THE LADSSSSSSSSSSSSSSSSSSSS!!!!"
Thomas Curtis, an Oxford-based Sunderland fan, is next in: "Tonight will be the icing on the cake for Sunderland if they can get the point required to all but secure safety. An roller coaster season as a fan. Giant killings, cup runs, amazing derby day memories and cult heroes created! C'mon lads. Finish the job! 2-0 (Colback, O'Shea)"
Let's hope that the majority of you are right this evening; another backing goals galore is Eimantas Noreikis: "I think Sunderland will not let this game be settled down as they will hunt for more history to go and win 4 successive games in a row.. I am going to go for a 5-0 win to Sunderland because I can't see many good finishers in the WBA side."
Hugh Seager is next in via e-mail: "I do like Norwich but it's inevitable with Sunderland's impressive form recently that their fate will be confirmed tonight. I think Sunderland will crush West Brom 5-1"
Steve Buck (@freshairsniper) is backing his Black Cats to complete their miracle survival: "I think it will be a nervous 2-2 with borini and wickham to score for Sunderland #notgoingdown"
Amir Maqsood's in-depth analysis has been e-mailed in: "Sunderland's recent form has been brilliant and Connor Wickham has hit great goal-scoring form aswell, I would like Sunderland to go down but at this moment in time it's looking very very unlikely unless they put in diabolical performances in the next two games. 2-1 Sunderland win. Borini to score both."
Commentary regular Chris Green from Huddersfield is backing a less exciting affair: "I see this game ending in a 1-1 draw."
Sunderland XI: Mannone, Vergini, Alonso, Brown, O'Shea, Cattermole, Colback, Larsson, Johnson, Borini, Wickham.

Damning indictment for Norwich fans from Peter, a Baggies supporter from Devon: "Let's face it. Both Sunderland and West Brom are safe. So let us have a nice open game of football and may the best team win - as long as it is the Baggies! Perhaps a 3-3 draw would be quite entertaining."
We'll have team news for you shortly, but in the meantime lets get some views, thoughts and predictions sent in before the game. Will either of these sides slip into the Championship next season?

Here is a breakdown of the repercussions of tonight's possible results for Norwich:
Indeed, whatever the result tonight, Norwich cannot be mathematically relegated. However, it will take a huge effort from them to stay up, much like the efforts of both teams on show tonight.
Sunderland, on the other hand, are two points above Norwich, with a +13 goal difference providing another advantage over the Canaries.
This game obviously has huge repercussions at the bottom of the league. Both sides are not yet completely safe, although West Brom have a three point and a +19 goal difference over 18th-placed Norwich.
