Watford manager Malky Mackay will pick from an unchanged squad as his in-form side prepare to welcome Scunthorpe.
Mackay saw his unfancied outfit reach third place in the Championship with an impressive 2-1 win at home to Ipswich in midweek and could name the same starting XI.
Marvin Sordell scored his sixth goal in his last eight games to see off Roy Keane's side and he will continue to partner Danny Graham while youngster Michael Bryan will hope to keep his place.
Bryan started for the first time this season in place of the injured Don Cowie and will battle it out with Will Buckley for the role against the Iron.
Cowie is a definite absentee as he begins a six-week spell on the sidelines after suffering medial knee ligament damage at Portsmouth last weekend.
Midfielder Ross Jenkins has recovered from an ankle injury and will hope to make the matchday 18.
Scunthorpe boss Ian Baraclough will be without defender Rob Jones when his side make the trip to Watford.
The towering centre-back displaced the broken bone in his hand during Tuesday's thrilling 3-2 win at Preston and was replaced at half-time by Michael Raynes.
Former Stockport defender Raynes is set to earn a starting role at Vicarage Road but on-loan Burnley midfielder Kevin McDonald looks certain to remain sidelined.
He has returned to Turf Moor to receive treatment on a back problem suffered during his first day's training with Baraclough's side.
Iron goalkeeper Joe Murphy, who was withdrawn with 17 minutes of Tuesday's match remaining because of a groin problem, has not yet been ruled out of the Vicarage Road clash.
