Manuwa and Anderson each entered this fight looking to remain near the top of the UFC light heavyweight division, although neither was likely to earn a title shot his next time out. He was most recently in action at UFC 204, stopping Ovince Saint Preux in the second round.
The win makes it two in a row for Manuwa, who has not lost since his knockout defeat to Johnson in September 2015.
Saturday's fight started with Manuwa taking the center of the Octagon, flat-footed, while Anderson was a ball of movement, constantly faking and shuffling side to side. The die was cast, however, that Manuwa didn't even need to load up on his punches to do a lot of damage if his punches landed.
Jimi Manuwa (17-2) had his patience pay off against Corey Anderson (9-3) with a one-punch knockout. Manuwa obliterated Anderson with a left hand and it was a done deal. The stoppage came at 3:05 in the first round.
As the American aimed to get his back off the fence, he was cuffed by a left hook from the Londoner and Anderson was out before he hit the canvas.
It only takes one @PosterboyJM gets it done on home soil by KO! "It's time for a title shot right now".
The call out of former heavyweight British boxing champion David Haye got a rise out of the crowd as did Manuwa asking for the chance to face the victor of the upcoming UFC 210 main event between current champion Daniel Cormier and Anthony Johnson. I want the victor out of DC and "Rumble" Johnson.
The 37-year-old closed out his conversation with commentator Dan Hardy by claiming that he is also keen on moving to the boxing ring to meet none other than David Haye.
