Dockers star Michael Walters has had his one-match suspension overturned at the AFL Tribunal on Tuesday night.
Walters was handed a one-match ban by the MRO for headbutting Melbourne's Jay Lockhart in last Saturday's clash.
But after a lengthy hearing, Walters was cleared by the Tribunal of any wrongdoing.
He is free to take on Carlton at Optus Stadium on Sunday night and eligible to win the Brownlow Medal.
