Adelaide skipper Taylor Walker is under an injury cloud after it was revealed the forward was forced to miss the last quarter of the JLT Series clash with Brisbane.
Walker had starred in the first three quarters of Adelaide's 39-point win, with 15 disposals, 10 marks and four goals - one of them a supergoal - at the final change.
But the captain was forced to miss the final term with hamstring tightness.
Coach Don Pyke confirmed the news after the match.
"He has got a little bit of hamstring tightness, which will get looked at," he said in his post-match press conference.
Walker has 15 days to shake it off before he is set to lead the Crows in their round one clash with the Giants.
