Winning Knockout of the Night on Saturday was returning heavyweight Todd Duffee. The bout marked Duffee's first fight in the UFC since May of 2010. His return was victorious as he bested Phil DeFries in the first round at 2:04 by TKO. Despite a start where DeFries connected with several hard punches as Duffee fought off a takedown along the fence, the AKA-fighter regrouped and landed a series of thudding shots in the center of the cage that ultimately rocked and sent DeFries down, prompting the referee stoppage. This marks the second time Duffee has earned a post-fight bonus award in the UFC.
Earning Submission of the Night was UFC bantamweight John Moraga, which he claimed by using a modified one-arm power guillotine to submit Chris Cariaso in the opening bout of the evening. After a relatively even back and forth for two rounds, Moraga was able to lock up an arm-in guillotine with a power guillotine grip that pushed Cariaso's back against the fence. After sitting into it and cinching down, Cariaso tapped at 1:11 of the third round. The win is the second in Moraga's UFC tenure while the award is his first.
