Former Ultimate Fighting Championship middleweight titleholder Anderson Silva returns from a lengthy and embarrassing PED-related suspension, and at age 40, any fight could conceivably be his last.
Silva will meet “The Ultimate Fighter” Season 3 winner and perennial middleweight contender Michael Bisping in the UFC Fight Night 84 featured attraction on Saturday at the O2 Arena in London. In the co-headliner, former Dream and Strikeforce champion Gegard Mousasi faces the resurgent Thales Leites. The rest of the four-fight main card shines the spotlight on undefeated Tristar Gym prospect Tom Breese -- he takes on Keita Nakamura -- and American Top Team bantamweight Brad Pickett, who has been paired opposite Francisco Rivera at 135 pounds.
