UFC 131

Brock Lesnar was scheduled to fight Dos Santos after their coaching stint on The Ultimate Fighter 13, but due to a reoccurring illness he was replaced by Carwin. Originally, a matchup between Carwin and Jon Olav Einemo was scheduled for this event. Einemo remained on the card and faced Dave Herman, who was pulled from a matchup with Joey Beltran as a result. Beltran was matched up with Aaron Rosa.

Court McGee was scheduled to fight Jesse Bongfeldt, but was forced to pull out due to a torn MCL while training with the Cesar Gracie’s camp and replaced by Chris Weidman.

Rani Yahya was scheduled to take on Dustin Poirier at this event, but withdrew due to injury on May 3, 2011 and was replaced by Jason Young.

Anthony Perosh was expected to face Krzysztof Soszynski at this event, but Perosh was forced from the bout with an injury and replaced by Igor Pokrajac. However, Pokrajac was forced to pull out of the bout due to injuries just days before the event and was replaced by Mike Massenzio.

On May 17, a torn muscle forced Mac Danzig out of his bout with Donald Cerrone. Promotional newcomer Vagner Rocha replaced Danzig.

UFC newcomer Dave Herman was originally slated to face Rob Broughton at this event, but Broughton was later replaced by Joey Beltran, who was later replaced with Jon Olav Einemo since Carwin replaced an injured Lesnar.
