Antonio Rodrigo Nogueira may have emerged from his UFC on FUEL TV 10 submission loss to Fabricio Werdum without a broken arm, but the legendary heavyweight will apparently require surgery to repair an injured elbow.

According to a report from the Brazilian publication, a follow up MRI revealed that Nogueira incurred ligament damage in his elbow and as a result, the 37 year-old fighter will undergo surgery today. The former PRIDE champ is expected to be sidelined up to eight weeks as a result.

After Noguiera was forced to tap-out to a second round armbar from Werdum, his coach Luiz Dorea tweeted “Our champion @ Minotauromma already did xray and thank God, did not fracture and already out of the hospital! Thank God!”

Nogueira had his arm severely broken in a December, 2011, bout with Frank Mir, who brought the fight to an end with a first round, Kimura. The BJJ black belt was sidelined for months as a result, and returned in October, 2012, and tapped out Dave Herman with an armbar in round two.

The decorated fighter is 2-3 in his last five bouts.
