When Marcus Brimage returns from an injury that will keep him down likely into 2014, he will do so in a new weight class. Brimage (6-2 MMA, 3-1 UFC) is rehabbing an Achilles tendon injury, but when he comes back, he is planning to drop from featherweight to bantamweight. Brimage’s manager, Lex McMahon, on Wednesday confirmed the plan to MMAjunkie.com after Brimage on Tuesday told Amy Barton of MMA DieHards’ Punch Drunk Radio of his decision to move down to 135 pounds. “Marcus has started his rehab and is working with a team of doctors, therapists, coaches and nutritionists to make certain that he returns to the octagon as soon as possible and in the best shape possible,” McMahon told MMAjunkie.com. “Current estimates are for a nine-month recovery. Upon his return, Marcus will fight as a bantamweight.” After appearing on Season 14 of “The Ultimate Fighter,” Brimage started his official UFC career 3-0 at featherweight with decision wins over Stephen Bass , Maximo Blanco and Jimy Hettes .
