By Cameron Gillon: Sergio Martinez had tests with his doctors last month to show whether his severe long-term knee injuries can handle boxing if he decides to carry on with the sport he has dominated for so long.
Martinez last fight was in June 2014 when he defended his WBC, Ring and Lineal titles against Miguel Cotto at Madison Square Garden, New York. Cotto came out sharp and Martinez wasn’t looking his self in the ring as Cotto put Martinez down three times in the first round and the fight looked like it wasn’t going to last more than a few more rounds. Martinez managed to recover and take the fight into the championship rounds before Martinez trainer decided he wasn’t going to win the fight and had nothing left to go for the knock-out on Cotto.

By Wepeeler: So I’ve let the dust settle from what was a monumental Miguel Cotto (39-4, 32 KO’s) win over WBC middleweight champion Sergio Martinez (51-3-2, 28 KO’s) last Saturday night at Madison Square Garden, in New York. I had watched and read all the pre-fight hype, and I’ve followed all the post-fight action as well. There seems to be an overabundance of people claiming that Sergio knees were shot and that Cotto should have an asterisk next to his Middleweight championship. This is straight ridiculous.
By Dan Ambrose: Sampson Lewkowicz, the adviser former WBC middleweight champion Sergio Martinez (51-3-2, 28 KO’s), says that the 39-year-old Martinez likely won’t be retiring from the sport just yet following his 10th round stoppage loss to Miguel Cotto last Saturday night. Lewkowicz says that if Martinez does retire, it won’t be a sudden thing where he just stops completely following a loss. Instead he’ll have a farewell fight in front of his fans in Argentina before stepping away from boxing.
