Barry Hall's career hangs by a thread after he was reported for another striking incident against Adelaide, taking the gloss off what would have been a fine four-goal effort against the Crows.

Hall delivered a short, sharp, left jab to Ben Rutten's chin as the pair tangled after the three-quarter-time siren at AAMI Stadium.

"There's definitely still some issues there with Barry Hall," Foxtel commentator Dwayne Russell said.

"I don't know too many leopards that can instantly change their spots - and Barry Hall is still a leopard."
