An unplanned match has been added to UFC 154, as John Maguire and Matt Riddle will square off. The card takes place November 17 from Montreal, with Maguire-Riddle slated for the prelims.
Originally, Stephen Thompson and Besam Yousef were locked in for the card. Thompson was injured and replaced by Riddle. Now, an injury has knocked Yousef out and Maguire has stepped in.
