New WBC and The Ring Magazine middleweight champion Sergio Martinez is set to have surgery to repair a damaged meniscus in his right knee next week in Madrid, Spain.
According to a report from Ronnie Nathanielsz of BoxingScene.com, Martinez had complained of discomfort in the knee prior to stepping in the ring with Julio Cesar Chavez Jr. this past Saturday.
The knee was further injured when Martinez was knocked down by Chavez Jr. in the 12th round. He would go on to survive the knockdown, reaching the final bell and securing a wide unanimous decision victory on the scorecards.
During the bout, Martinez also suffered a broken left hand (believed to have happened around the fourth round) and a deep laceration on the top of his head.
While there is no timetable for his return, the WBC has stated that he is definitely done fighting in 2012.
This should come as little shock; Martinez was not expected to return to the ring before 2013 prior to the injuries being announced.
A rematch with Chavez Jr. has been discussed for Cowboys Stadium in Dallas next year and would provide the most lucrative non-Floyd Mayweather fight.
But Martinez has previously expressed reservations about a fight in Dallas, which is Chavez Jr.'s backyard, and has has indicated that his preference would be to instead face Miguel Cotto. That fight would be pending weight issues being worked out between the fighters.
