Celtic wait on injured stars

Celtic have a number of injury concerns ahead of the Old Firm derby at Ibrox.

Jan Vennegoor of Hesselink and Paul Hartley are extremely doubtful with hamstring injuries, the same problem that could also keep Scott Brown on the sidelines.

Gary Caldwell (knee) returned to training yesterday and will be assessed by the medical staff but Maciej Zurawski is in the frame for a return.

Caldwell’s recovery could solve a problem at right-back with Jean-Joel Perrier Doumbe (Achilles), Mark Wilson (knee) and Paul Caddis all out.

Provisional squad: Boruc, Kennedy, Caldwell, McManus, Naylor, McGeady, Nakamura, Donati, Jarosik, Killen, Scott Brown, McDonald, Mark Brown, Riordan, Zurawski, Sno, O’Dea, O’Brien.
