Crows forward Taylor Walker’s knee injury is expected to sideline him for four or five games.

Walker, who sprained the posterior cruciate ligament in his right knee when tackled in the second term of Sunday’s game against Brisbane Lions, visited a specialist today.

Crows physical performance manager Stephen Schwerdt said Walker’s PCL injury was at the lower end of the scale and did not need a brace.

Walker, 21, returned to the Adelaide line-up last weekend after two matches back in the SANFL with Norwood.
