UFC 316: Dvalishvili submits O'Malley in rematch to retain bantamweight title

Merab Dvalishvili (20-4) and Kayla Harrison (19-1) got their opponents, Sean O'Malley (18-3) and Julianna Peña (13-6), respectively, to tap out at UFC 316. Women's bantamweight legend Amanda Nunes, who will be enshrined in the UFC Hall of Fame later this month, jumped into the Octagon immediately after Harrison's title win and let the crowd in Newark, New Jersey, know she is ready to unretire to challenge Harrison.

Elsewhere on the UFC 316 card, former Bellator champion Patchy Mix (20-2) saw his UFC debut upended by Mario Bautista (16-2), who is ranked No. 6 bantamweight in ESPN's divisional rankings.
