Harrison (19-1 MMA, 3-0 UFC) claimed the bantamweight title by submitting Julianna Peña (12-6 MMA, 8-4 UFC) in Saturday's UFC 316 co-main event. Immediately after her win, she welcomed Nunes into the octagon for a faceoff.

Kayla Harrison realized her dream on Saturday night after a lopsided mauling leading to a submission finish over Julianna Peña to become champion at UFC 316. It was evident from the first exchange that Harrison was a much more physically imposing fighter as she worked her way inside and brought Peña down to the canvas.

Kayla Harrison, the two-time Olympic judo gold medalist and two-time PFL lightweight champion, became a UFC champion with a second-round submission win over bantamweight titleholder Julianna Peña.
