The bout at UFC 112 was deemed close enough that Edgar's first title defense took the form of a UFC 118 rematch against Penn on August 28, 2010. Edgar defeated Penn via unanimous decision to retain the UFC Lightweight Championship, this time with no controversy after taking Penn down multiple times and out-striking him throughout all five rounds. All three judges scored the bout 50–45 for Edgar, making him the second fighter to defeat Penn in the Lightweight division (the other being Jens Pulver) and the second fighter ever to beat Penn twice (the other being Georges St-Pierre).
