Infected wisdom teeth have KO'd John Lineker from Saturday's UFC 219 undercard fight with Jimmie Rivera.
Lineker (30-8) was scheduled to have emergency surgery. Lineker was Rivera's second opponent to withdraw because of injury. Rivera (21-1) was supposed to fight Dominick Crus, but Cruz injured his arm in November.
Lineker-Rivera had been scheduled as part of the main card at T-Mobile in Las Vegas. The main fight pits Cris "Cyborg" Justino against Holly Holm for the featherweight title.
Lineker apologized via MMAjunkie.com:
"I am really sad to have to withdraw from my fight with Rivera. I felt a little pain in the beginning of the week, went to the dentist and got treated, but (the pain) just kept getting worse. I came to Las Vegas early and tried to stay in the fight, but it was simply impossible.
"I would like to apologize to Rivera. I know how much it sucks when this happens. I want to apologize to Sean Shelby and the UFC. I begged them for the fight, and they agreed, and now I feel horrible to have to withdraw. And I need to apologize to the fans."
