Defensive crisis for Celtic

Celtic have no recognised first-team full-backs for tomorrow's SPL clash against Hearts.

Gary Caldwell should continue to deputise for Mark Wilson (knee) and Jean-Joel Perrier-Doumbe (Achilles) at right-back, but left-back Lee Naylor will be out for around three weeks with a calf strain.

Central defender Darren O'Dea may fill in for Naylor tomorrow if he brushes off the effects of a virus, while centre-back John Kennedy is expected to be out for three months after injuring his knee again, and playmaker Shunsuke Nakamura (knee) is still on crutches.

Provisional squad: Boruc, M Brown, Caldwell, McManus, S Brown, McGeady, Hartley, Donati, Jarosik, McDonald, Vennegoor of Hesselink, Zurawski, Caddis, Killen, Riordan, Pressley, Sno, O'Dea.
