Chael Sonnen and Tito Ortiz have already fought once, in January of 2017, but apparently, their beef is not yet settled.

Since their first fight, which Ortiz won via first-round submission, the pair have continued to go back and forth, raising question as to whether we might see them fight again.

The latest shot in this ongoing rivalry was fired by Sonnen.

Speaking on Twitter on Sunday night, the three-time UFC title challenger took to Twitter where he once again challenged Ortiz to a fight.

Hey stupid, @titoortiz straight up. Do you want to fight or not?

“Hey stupid, [Tito Ortiz] straight up. Do you want to fight or not?” – Chael Sonnen on Twitter.

Tito Ortiz last fought in November, in the main event of the debut show from Oscar De La Hoya’s Golden Boy MMA, when he picked up his first, long-awaited win over Chuck Liddell with a first-round knockout. His next most recent fight was against Sonnen. The former UFC light heavyweight champion and UFC Hall of Famer is 20–12–1.

Chael Sonnen, meanwhile, is 31-16-1. He last fought in October, in the main event of Bellator 208, when he was stopped by heavyweight legend Fedor Emelianenko in the second round of Bellator’s Heavyweight Grand Prix. This loss was preceded by consecutive defeats of MMA legends Quinton “Rampage” Jackson and Wanderlei Silva.
