Mitchell submits Luna in final seconds to cement bantamweight fresh start

Bryce Mitchell (19-3) ground out a gritty submission victory over late replacement Santiago Luna (8-1) at UFC Fight Night 278 in Las Vegas on Saturday, locking in an arm-triangle choke with fewer than ten seconds left on the clock to seal a unanimous statement in his new weight class.

The fight was far from a crowd-pleaser for most of its duration, with Mitchell controlling Luna on the mat for extended stretches. Mitchell was candid about why the striking output was limited, explaining in his post-fight interview that the sustained grappling effort had drained his arms well before the finish.

“I’m squeezing so hard with my arms the whole fight; it was actually hard for me to elbow and punch him,” Mitchell said. “When he moves, I finally get to punch, but I don’t get to do very big punches because he is moving. So, you get a heavy grappling match, an exhausting pace, with very little room for error. He made a slight mistake, and I was able to capitalize on it.”

The original opponent, Victor Henry, was forced out with an injury, and Luna stepped in on short notice — arriving undefeated at 8-0 before Saturday’s contest.

Mitchell’s path to bantamweight was a turbulent one. He had climbed into the featherweight rankings before suffering his first professional loss to future double-champion Ilia Topuria in 2022. He then dropped two of his next four bouts, with a brutal knockout defeat to Jean Silva last year prompting the decision to move down to 135 pounds. He has now won both appearances at the new weight, and the Arkansas native believes the division suits him far better physically.

“I think I’m just less undersized [at bantamweight],” Mitchell said. “I don’t think that I’m the bigger guy in there. I just think that I’m used to being the smaller guy, but now I’m just medium size. So, it makes me look bigger. Thank God I’m not fighting guys that are 200 pounds. I’m a real ‘35er.”

The victory keeps Mitchell’s momentum building in a division where he appears increasingly settled, both physically and mentally, as he looks to work his way back into contention.
