Philadelphia 76ers star Joel Embiid will undergo surgery on Friday after suffering a torn radial collateral ligament in the fourth metacarpal in his left hand.

Embiid, who was already ruled out of Thursday's NBA showdown against Eastern Conference rivals the Boston Celtics, will be re-evaluated in 1-2 weeks.

The All-Star dislocated his left ring finger in the opening quarter of Monday's 120-113 victory over the Oklahoma City Thunder.

Embiid, however, continued and finished with 18 points, nine rebounds and eight assists in Philadelphia.

"All of a sudden, we're different," 76ers head coach Brett Brown said prior to Thursday's game. "We're just different. I look at this as an opportunity.

"Nobody's crying. This is not a 'woe is me' moment, not for me, at all. And not for my players. We'll take what we have, and what we have, I love."

Embiid has been averaging 23.4 points, 12.3 rebounds and 3.3 assists per game for Eastern Conference contenders the 76ers (24-14) this season.
