An MRI last Monday revealed that Lin had a chronic, small meniscus tear in his knee. He waited several days before having surgery, hoping that he could play with the tear.
Though the swelling went down, the pain never did, and after testing the knee again Friday and Saturday, he decided to have the surgery.
Lin is expected to miss the rest of the regular season and the first round of the playoffs -- assuming the Knicks qualify.
"Praise God for a successful surgery! Now on the road to recovery! Lets gooo. Much love to all the fans for your support and kind words," Lin wrote on his Facebook page.
The surgery likely ends Lin's storybook season.
The Knicks signed the undrafted guard and former Harvard standout after he was waived by two teams in the preseason. Lin was buried on the Knicks bench for his first six weeks with the team, even spending a short stint with the Knicks' D-League affiliate. But, given a chance to play in late February, he led New York to seven straight wins and attracted worldwide attention in the process.
The Knicks will continue to turn to 32-year-old Baron Davis in place of Lin.
Davis is averaging 8.5 points, 5.5 assists and four turnovers per game as the Knicks starter.
Stoudemire is expected to be out 1-3 weeks with a bulging disk in his lower back. He is undergoing non-surgical treatment. Jeffries has missed six games due to a right knee injury. He is expected to test his knee by running on it this week and will get a clearer picture of when he may return then.
New York enters play Monday 2½ games ahead of the Milwaukee Bucks for eighth place in the Eastern Conference.
