UFC fighter Quinton "Rampage" Jackson, who had a breakthrough role as B.A. Baracus in 2010's The A-Team, is set for his final fight in the Octagon.

Jackson, who scored the biggest role of his acting career when he assumed the role made famous by Mr. T on television in the 1980s, will fight 32-year-old Glover Teixeira on October 13 in Rio de Janeiro, Brazil at UFC 153. The fight will be the last of Jackson's UFC contract, and all indications are that he does not plan on continuing his mixed martial arts career beyond that point.

A former UFC Light Heavyweight Champion with a mixed martial arts record of 32-10, Jackson has been appearing in film and on television since 2005, when he played Matador in "Confessions of a Pit Fighter," one of several films in which he's appeared alongside Hector Echavarria (others include Hell's Chain, Death Warrior, and the upcoming Duel of Legends). He's also due to appear later this year in "Fire With Fire," which stars Josh Duhamel, Rosario Dawson and Bruce Willis. His biggest role by far, however, was in "The A-Team," in which he starred alongside Liam Neeson, Bradley Cooper and Jessica Biel in a film that grossed more than $177 million worldwide.

Jackson has remained a top draw for the UFC, challenging Jon "Bones" Jones for the light heavyweight championship last year at UFC 135. However, it appears that his fighting days are close to over.

He just has one more mountain to climb.
