Georges St-Pierre’s reign as UFC middleweight champion is officially finished after just a shade over one month.

In a statement released on Thursday night, St-Pierre confirmed that he’s relinquished his title, citing health reasons.

St-Pierre defeated Michael Bisping in the UFC 217 main event to become the 185-pound champion in his first fight at the weight class. This news comes a day after GSP indicated that he wasn’t sure he’d compete at middleweight again.

St-Pierre also recently announced that he was dealing with ulcerative colitis, something that Dana White had said would keep the Canadian sidelined indefinitely.
