BARON DAVIS has torn the anterior cruciate and medial collateral ligaments in his right knee, a potentially career-threatening injury for the Knicks' 33-year-old point guard.

The Knicks said Davis will have surgery this week and is expected to be out a year after an MRI on Monday also revealed a partial tear of the patella tendon.

Davis was hurt Sunday in the Knicks' 89-87 victory over Miami, crumbling to the court when his knee gave out as he dribbled upcourt on a fast break in the third quarter. Teammates quickly waved for help, and some players looked away as replays of the gruesome injury were shown on the overhead video board.

"I didn't want to watch," Heat forward Chris Bosh said. "I kind of heard the reaction and then when they were playing it back on the Jumbotron like 80 times everybody could hear the reaction of the crowd. You never want to see guys go down like that. I just hope that everything's OK for him and he recovers well."

Davis became the starter after Jeremy Lin needed surgery to repair torn cartilage in his left knee on April 2.
