Adelaide captain Taylor Walker has been withdrawn from the Crows' match against GWS on Sunday afternoon, after failing to overcome some hamstring tightness.

โ€œTex was really close to playing,โ€ Crows General Manager High Performance Matt Hass said.

โ€œHe completed all his training during the week, however, the Club has chosen to take a no-risk approach and will now aim for him to be fit for Round Two.โ€

Riley Knight has replaced Walker in the Adelaide 22.
