An MRI revealed extensive ligament damage in his left elbow that will require Nogueira to undergo surgery on Friday.
Nogueira also required surgery following a Kimura submission loss to Frank Mir in late 2011. That surgery required 16 screws in his humerus, but Nogueira still managed to return to the Octagon 10 months later to defeat Dave Herman.
The surgery on Friday is expected to keep Nogueira sidelined for about eight weeks.
