LAS VEGAS (CBSDFW.COM/AP) – Chuck Liddell and Tito Ortiz say they are coming out of retirement for a third fight in their mixed martial arts rivalry.

Liddell and Ortiz confirmed Thursday they plan to meet in the cage later this year.

The 48-year-old Liddell and 43-year-old Ortiz are among the most accomplished fighters in MMA history and pioneers in their sport. Their second bout was in December 2006, when Liddell stopped Ortiz at UFC 66.

Liddell hasn’t fought since June 2010, when he retired following five losses in six bouts. Earlier this year, Liddell appeared on the inaugural season of CBS reality television show “Celebrity Big Brother,” where he was the first famous contestant to be eliminated.

Ortiz retired in January 2017 after beating Chael Sonnen in the Bellator promotion.

The bout will be staged by Oscar De La Hoya’s Golden Boy Promotions, which is entering MMA. A date and location for the fight haven’t been set.
