Sunderland boss Martin O'Neill could be without a trio of key players.

Defender Wes Brown (medial ligament) and midfielder David Vaughan (ankle ligament) could be sidelined for several weeks after suffering injuries in Sunday's FA Cup tie with Middlesbrough, while skipper Lee Cattermole missed that game with a hamstring problem which could keep him out again.

O'Neill will hope Fraizer Campbell has suffered no reaction to his first senior appearance in 17 months following a long-term knee problem, and that fellow striker Connor Wickham recovers from his exertions at the weekend with Nicklas Bendtner still out with a fractured nose.

Norwich have no fresh injury worries.

Goalkeeper John Ruddy, Wales striker Steve Morison and midfielders Bradley Johnson and Andrew Surman were all rested for the FA Cup win at West Brom and will come back into contention, along with on-loan Tottenham full-back Kyle Naughton, who was ineligible.

Striker James Vaughan has recovered from his long-term knee injury but is expected to need more time to get fully match fit, as is defender Elliott Ward.
