It turns out Yuri Foreman's right knee is in worse shape than originally thought.
The former WBA 154-pound champ is scheduled to have reconstructive ACL surgery on Friday at the NYU medical center, ESPN.com's Dan Rafael reported.
Foreman's manager Murray "Schpipples" Wilson said Foreman will also have cartilage moved.
Foreman's knee gave out causing him to fall to the canvas in the seventh round during his fight against Miguel Cotto on Saturday at Yankee Stadium. Trainer Joe Grier threw in the towel in the eighth round to stop the fight, but referee Arthur Mercante Jr. ignored it.
The fight continued after the ring was cleared.
Foreman said during the post-fight press conference he injured his knee as a child. He's worn a brace as a "protective" measure.
The injury won't be career-threatening and Foreman could be back in the ring in 2011, according to Wilson.
"The doctor said, 'In six months, you'll be ready to rumble.' In four months, he should be able to walk around without a problem and exercise, but it's probably six months to fully recover. We're talking about maybe a fight in February," Wilson told ESPN.com.
