Houston Rockets forward Luc Mbah a Moute is likely to miss the first round of the Western Conference playoffs with a dislocated right shoulder, a league source told ESPN's Adrian Wojnarowski.

Mbah a Moute underwent an MRI on Wednesday morning in Houston and a precise timetable for his return is unclear, the source said. Houston (65-16) will be the top seed in the West playoffs.

Mbah a Moute suffered the injury in the second quarter Tuesday night and didn't return to the Rockets' 105-99 win over the Los Angeles Lakers.

He suffered the injury while dunking in the second quarter. He held his shoulder in pain and immediately left the game with 6:46 remaining in the first half.

A 10-year veteran, Mbah a Moute missed 15 games after dislocating his right shoulder in mid-December.

Mbah a Moute entered Tuesday averaging 7.5 points and 25.6 minutes per game this season. He had two points and two rebounds when he departed with the injury.
