Defender Gael Givet (knee) is also doubtful while Rovers are monitoring the fitness of winger Morten Gamst Pedersen, who has a rib problem.

Vince Grella (groin) is absent and knee-injury victims Brett Emerton and Steven Reid have already been ruled out for the rest of the season.

Provisional squad: Robinson, Brown, Bunn, Ooijer, Khizanishvili, Nelsen, Samba, Simpson, Warnock, Givet, Olsson, Villanueva, Tugay, Andrews, Diouf, Treacy, Mokoena, Dunn, Haworth, McCarthy, Roberts, Pedersen.
