Sergio Martinez retires
Former middleweight world champion Sergio Martinez has retired from boxing.
The 40-year-old Argentine brings his glittering career to an end after 17 years as a professional.
Martinez's retirement was expected. He had not fought since last June after losing the 160-pound world title by a one-sided 10th-round knockout to Miguel Cotto.
It was his first defeat since losing to Paul Williams in December 2009, a run that began with 'Marvellous' becoming WBC and WBO champion after out-pointing Kelly Pavlik.
Martinez then avenged the loss to Williams with a stunning second-round knockout and went on to gain the WBC Diamond strap and make five defences.
Elbow and knee injuries have taken its toll over the past few years.
He confirmed his retirement at the International Hall of Fame weekend banquet, in Canastota, New York. He has a professional record of 51-3-2 with 28 knockouts.
