Bantamweight contender Jimmie Rivera has a new opponent for UFC 219 on Dec. 30 at T-Mobile Arena.
John Lineker has agreed to step in for injured former champ Dominick Cruz to face Rivera, UFC officials confirmed on Tuesday.
Cruz pulled out of the fight because of a broken arm he sustained earlier this month.
Rivera has won 20 straight fights, including five since signing with the UFC.
Lineker has won five of six since moving back up to 135 pounds, with the only loss against current champ T.J. Dillashaw.
UFC 219 includes a women’s featherweight title bout between champion Cris “Cyborg” Justino and former bantamweight champion Holly Holm.
