On a card featuring a rather famous knee in the main event, it is a knee that has knocked out one of the undercard’s competitors.
Stephen Thompson has suffered a knee injury and has been forced out of his UFC 154 fight against Besam Yousef, sources close to the fight on Friday confirmed to MMAjunkie.com. MMA Fighting first reported the news.
The UFC has not yet announced Thompson’s injury, and it is not known if a replacement will be sought to face Yousef on three weeks’ notice.
