Skipper Lee Cattermole and record signing Asamoah Gyan are major doubts for Sunderland's Barclays Premier League clash with Blackburn tomorrow.
Midfielder Cattermole is struggling once again with a back-related hamstring problem which hampered last season, while Gyan suffered a hamstring injury during Tuesday's 2-0 home defeat by Blackpool.
Defender Nedum Onuoha is likely to miss out with a similar problem, but Titus Bramble, who played almost an hour of Tuesday's game as a substitute, is available after getting further action under his belt in a behind-closed-doors friendly with Gateshead yesterday, while Danny
Welbeck (neck) is also expected to be fit.
John Mensah (ankle) remains a week away from a return, but Michael Turner and Fraizer Campbell (both knee) are still on the casualty list.
Provisional squad: Gordon, Mignolet, Bardsley, Richardson, Angeleri, Ferdinand, Bramble, Da Silva, Cattermole, Meyler, Riveros, Henderson, Malbranque, Elmohamady, Welbeck, Zenden, Bent, Gyan, Adams, Cook, Reed.
Blackburn goalkeeper Paul Robinson is set to be sidelined for the next three weeks after aggravating a calf injury in his side's 3-1 win at West Brom on Tuesday.
The former England number one had to be replaced by Mark Bunn at the Hawthorns and will miss tomorrow's match at Sunderland and is also expected to miss games against Liverpool, QPR and Chelsea.
Striker Nikola Kalinic is suspended for the next three matches following his sending-off against the Baggies, while manager Steve Kean expects to be able to recall Christopher Samba following an ankle problem.
Provisional squad: Bunn, Salgado, Nelsen, Samba, Givet, Olsson, Emerton, Pedersen, E-H Diouf, Dunn, Benjani, Hoilett, MB Diouf, Doran, Morris, Hanley, Fielding.
