Harrington out 3-4 months

Al Harrington's run with the New York Knicks is likely over.

The team announced that the forward will undergo arthroscopic right shoulder surgery on Thursday and will be sidelined three to four months. The procedure will be performed by team orthopedist Dr. Answorth Allen.

Harrington becomes a free agent this summer, and the Knicks have been positioning themselves for years to go after a premier free agent. It's no secret that Cleveland Cavaliers superstar LeBron James is on the top of their wish list.

Just last week, Harrington said that he would try to play through what he called inflammation in his shoulder. He acknowledged that offseason surgery was an option, but that timetable has been pushed up.

Harrington, who is averaging 17.7 points and 5.6 rebounds this season, was acquired in November 2008 in a trade that sent Jamal Crawford to Golden State. It was the second time that Knicks president of basketball operations Donnie Walsh traded for Harrington. As general manager of the Pacers, he acquired him from Atlanta in the summer of 2006.

That deal returned Harrington to Indiana, where Walsh drafted him as a high schooler with the 25th pick in 1998.
