Chicago Bull guard Derick Rose suffered a torn ACL in his left knee and will miss the rest of the season, the team announced Saturday.
Rose suffered the injury while trying to leap off his left foot in the lane with 1:22 left in Saturday's playoff game against the Philadelphia 76ers.
Rose was helped off the court before the Bulls sealed their 103-91 Game 1 win. Rose had 23 points, nine rebounds and nine assists when he was injured.
Team medical personnel immediately rushed out and tended to Rose for several minutes as he was writhing in pain near the baseline before helping him to the locker room. Rose was taken to the hospital, where MRI results confirmed the Bulls' worst fears.
The 23-year-old Rose played in just 39 of the Bulls' 66 regular-season games because of turf toe, back spasms, pulled groin and foot injuries. He hasn't played more than two games in a row since suffering a foot injury on March 12.
Rose becomes the fifth player named to Team USA's 20-man preliminary roster to have been ruled out before May.
Orlando's Dwight Howard (back), Portland's LaMarcus Aldridge (hip) and the Los Angeles Clippers' Chuncey Billups (Achilles) also suffered serious injuries during the lockout-shortened season requiring surgery, while the Dallas Mvericks' Lamar Odom has been eliminated from contention for this summer's Olympic team because of the longstanding struggles that prompted the Mavericks to deactivate Odom for the rest of the season.
