Sunderland boss Martin O'Neill is waiting for news of key duo John O'Shea and Lee Cattermole ahead of Tuesday's Premier League clash with QPR.
Central defender O'Shea limped out of Saturday's 4-2 home defeat by West Brom with a calf problem and is a major doubt, while midfielder Cattermole's chances of playing are not a great deal better after he aggravated a knee injury during the same game.
O'Neill also admitted he has a series of other knocks which are a concern, but declined to elaborate as he prepared his side to face a team managed for a first game by Harry Redknapp.
Harry Redknapp should be able to call on** **QPR captain Park Ji-sung for his first game in charge at Sunderland.
Park failed to recover from a knee problem in time for Saturday's defeat at former club Manchester United but is expected to be in contention for the Barclays Premier League trip to the Stadium of Light.
Jose Bosingwa is thought to have recovered from the virus that ruled him out at the weekend but strikers Bobby Zamora (hip) and Andrew Johnson (knee) are longer-term concerns.
Sunderland: Mignolet, Westwood, Bardsley, O'Shea, Kilgallon, Cuellar, Bramble, Rose, Cattermole, Gardner, Colback, McClean, Larsson, Sessegnon, Saha, Fletcher, Campbell, Wickham, McFadden.
QPR: Green, Cesar, Onuoha, Hill, Nelsen, Ferdinand, Mbia, Fabio, Bosingwa, Traore, Derry, Diakite, Park, Granero, Taarabt, Hoilett, Faurlin, Wright-Phillips, Ephraim, Mackie, Cisse.
