Don't call it a comeback, he's been here under contract for years.
Former Ultimate Fighting Championship (UFC) light heavyweight champion Quinton Jackson is returning to Bellator MMA, despite a brief pit stop inside the Octagon at UFC 186, after settling his differences with the Viacom-owned mixed martial arts (MMA) organization.
From the promotion's official statement:
Following an amicable agreement to settle the litigation between the two parties, the always entertaining and exciting Quinton "Rampage" Jackson is returning to Bellator. Bellator MMA is thrilled to have "Rampage," one of the most recognizable fighters in the history of the sport, joining a very competitive light heavyweight division featuring champion Liam McGeary, Phil Davis, King Mo, Tito Ortiz, Emanuel Newton, Linton Vassell among others.
