The event was the second that the UFC has hosted in Birmingham, the first was UFC 89 back in 2008 also featuring Chris Leben in the main event.
After several tentatively scheduled 2011 events  at various locations around the United Kingdom did not materialize, including Glasgow, Liverpool, London as well as a planned return to Ireland, it was expected that the organization would not hold an event in the area during 2011.
Mark Scanlon was expected to face James Head at this event. However, Scanlon was pulled from the bout and replaced by promotional newcomer John Maguire Then, on September 28, Head himself pulled out of the fight due to an undisclosed injury and was replaced by Justin Edwards.
Pascal Krauss was expected to face John Hathaway at this event. However, on August 30 Krauss pulled out of the bout citing a shoulder injury, and was replaced by Matt Brown. Then on October 17 it was announced that Hathaway was forced to withdraw from the bout due to injury as well. As a result, Brown was pulled from the event and will face Seth Baczynski at UFC 139.
Phil De Fries was expected to face Oli Thompson at this event. However, on October 17 it was announced that Thompson was forced to withdraw from the bout due to injury. De Fries fought Rob Broughton at this event instead.
Anthony Njokuani was scheduled to fight Paul Taylor on the main card. However, Taylor sustained a whiplash injury during a minor traffic collision on November 1 forcing him from the bout.
