Adelaide captain Taylor Walker has been withdrawn from the Crows’ match against GWS on Sunday afternoon, after failing to overcome some hamstring tightness.

“Tex was really close to playing,” Crows General Manager High Performance Matt Hass said.

“He 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.”

Riley Knight has replaced Walker in the Adelaide 22.
