UFC 131
UFC 131: dos Santos vs. Carwin was a mixed martial arts event held by the Ultimate Fighting Championship on 11 June 2011 at the Rogers Arena in Vancouver, British Columbia, Canada. Background

Brock Lesnar was originally scheduled to face Junior dos Santos after their coaching stint on The Ultimate Fighter 13, but due to a recurring illness, Lesnar was replaced by Shane 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 and was replaced by Chris Weidman

Rani Yahya was scheduled face Dustin Poirier at this event, but withdrew due to injury on 3 May 2011 and was replaced by UFC newcomer 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. The Soszynski/Pokrajac bout was later rescheduled for UFC 140, where Pokrajac won by knockout. On 17 May 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 John Olav Einemo since Carwin replaced an injured Lesnar. UFC 131 featured two preliminary fights live on Spike TV, and the remainder of the preliminary bouts streamed on Facebook and YouTube. Results
