UFC 124: St-Pierre vs. Koscheck 2 was a mixed martial arts pay-per-view event held by the Ultimate Fighting Championship on December 11, 2010 at Bell Centre in Montreal, Quebec, Canada.

A training injury forced Jason MacDonald out of his fight with Rafael Natal on October 20, 2010.

[4] On October 26, 2010, Anthony Waldburger had to pull out of his fight with Matthew Riddle due to an injury.

[6] UFC 124 featured live preliminary bouts streamed on UFC.com rather than Spike TV due to the 2010 Spike Video Game Awards being aired in the same time slot.

[8] Dana White stated after that he would never do this again and said "The real fight of the night belonged to Matt Riddle and Sean Pierson".
