Tuivasa scores walk-off KO over Lewis

Tai Tuivasa scored a highlight-reel finish of Derrick Lewis in the UFC 271 co-main event.

Tuivasa knocked out Lewis at the 1:40 mark of the second round in a heavyweight bout Saturday night in Houston.

The heavyweights exchanged massive shots throughout the fight before Tuivasa rocked Lewis and then face-planted him with a vicious elbow to the face.

This was by far Tuivasa's biggest win to date. He entered as the No. 11-ranked heavyweight and will likely move into the top five after stopping Lewis, who was No. 3.

The Australian is now riding a five-fight winning streak and hasn't lost since 2019.

Lewis, who resides in Houston, is now 1-2 over his past three Octagon outings. His most recent loss before Saturday came in an interim title bout against Ciryl Gane last August. After that fight, "The Black Beast" returned to the win column against Chris Daukaus in the final UFC bout of 2021.
