ADELAIDE captain Taylor Walker says club medicos will decide whether he plays in the club's season opener against Greater Western Sydney.
Walker suffered tightness in a hamstring and left the field during Adelaide's JLT Community Series win against the Brisbane Lions last Saturday.
"I will be honest, I will be guided by the PPT (physical performance team) because I have never had a hamstring (injury)," Walker told radio station Triple M on Tuesday.
"I'm backing the doctors in to make a clear and good decision."
Walker had kicked three goals against the Lions but didn't feature after three-quarter time.
"I left the ground with a bit of tightness in the hammy and pulled up really well, so good signs early," he said.
The injury concern is the latest to hit the Crows ahead of their round one match against the Giants on March 26.
Walker said he expected his vice-captain Rory Sloane, who didn't play a pre-season game after fracturing an eye socket in a training mishap, to front against the Giants.
But midfielders Scott Thompson (shoulder) and Brad Crouch (hamstring) and defenders Jake Lever (hamstring) and Kyle Cheney (groin) all face battles to prove their fitness after all missed the three-game pre-season series.
