Sources - Heat's Jimmy Butler expected to miss several weeks - ESPN

Miami Heat star Jimmy Butler is expected to be sidelined for several weeks with a right MCL injury suffered in Wednesday's loss to the Philadelphia 76ers, sources tell ESPN's Adrian Wojnarowski.

Butler was hurt on the final play of the first quarter in Philadelphia. He remained in the game but scored a total of 12 points the rest of the way on 3-for-14 shooting, as Miami's offense dried up after taking a 12-point halftime lead, allowing Philadelphia to come from behind and close a 105-104 victory.

The Heat will host the Chicago Bulls on Friday night, with the winner securing the No. 8 seed in the Eastern Conference and a first-round playoff series matchup against the Boston Celtics.

The Heat officially ruled Butler out for the Bulls game Thursday afternoon. Also ruled out was point guard Terry Rozier, who continues to deal with a strained neck.

After leaking out for a potential fast-break layup in the first quarter, Butler tried to fake out Philadelphia's Kelly Oubre Jr. to attempt to make a layup, only to have his knee buckle after it appeared Oubre landed on it, causing Butler to fall to the floor in pain.

Butler said after the game that he would undergo an MRI on Thursday, adding "I hope that I wake up tomorrow and can still stick-and-move. Right now, I can't say that's the case."

Butler, a former Bull and Sixer, scored 20.8 points in 60 games for the Heat this season. The six-time All-Star said he stayed in Wednesday's game because he thought the "adrenaline would kick back in" and he would feel healthy enough to play at his usual level.

Aside from the injuries to Butler and Rozier, Heat shooting guard Duncan Robinson also has bothered by a back injury. He was cleared to play Wednesday but did not appear in the game.
