UFC newcomer Vagner Rocha will replace the injured Mac Danzig against Donald Cerrone at UFC 131.
The event takes place June 11 at the Rogers Arena in Vancouver.
The organization announced the news late on Tuesday evening. Danzig pulled out of the fight on Tuesday due to a muscle tear sustained while training for the fight.
Rocha is a veteran of Strikeforce and Bellator and a black belt under Pablo Popovitch.
The fight is currently scheduled for the Spike TV broadcast.
