The Philadelphia 76ers may not have star Joel Embiid for game 5 against the Washington Wizards, which is on Wednesday.

76ers head coach Doc Rivers says he will have an MRI on Tuesday, after suffering a right knee injury on Monday night.  In the first quarter, Embiid landed on the court hard after he was blocked by Wizards center Robin Lopez.  The 4-time All-Star finished out the first quarter but left the game after that.  He's averaging 30 points a game in the series.
