It’s been 11 months since Manny Pacquiao was knocked out by Mexican rival Juan Manuel Marquez, leading some to believe that retirement was near for the Filipino boxing sensation.

On Saturday, Pacquiao, 34, will attempt to prove naysayers wrong when he takes on Brandon Rios, an American boxer seven years his junior, at Cotai Arena in Macau. Pacquiao, who has won 10 world titles in eight weight classes, has been consistently ranked as one of the best pound-for-pound boxers in his generation.
