UFC fighter Chael Sonnen had several inches of his colon removed during emergency surgery on Nov. 15 - one day before his first-round loss to Rashad Evans at UFC 167, according to a source.
Sonnen talked to TSN about the procedure during a taping of TSN's Off The Record on Wednesday, after host Michael Landsberg revealed that a source told him about it.
"It's a little bit of a surprise that you had that information," replied Sonnen, who would not confirm or deny whether he had undergone surgery.
Despite the alleged medical emergency, Sonnen did not withdraw from the scheduled matchup in Las Vegas on Nov. 16 and was defeated in a first-round TKO.
"When I sign a contract to fight, I'm agreeing to fight a guy on a certain day at a certain time and in a certain venue," he continued. "It's my job to feel good when I go out and do it and if I don't that may play a hand in the fight."
Landsberg's full interview with Sonnen will air Wednesday at 5pm et/2pm pt on TSN.
