Thomas ruled out for remainder of NBA postseason

Updated: 

Boston Celtics star Isaiah Thomas is out for the rest of the NBA postseason.

The Celtics announced on Saturday that the second team All-NBA guard re-aggravated a hip injury, specifically a right femoral-acetabular impingement with a labral tear, during game two of the Eastern Conference Finals against the Cleveland Cavaliers on Friday.

"Isaiah has worked tirelessly to manage this injury since it first occurred," Celtics chief medical officer Dr. Brian McKeon said in a statement.

"The swelling increased during the first two games against Cleveland, and in order to avoid more significant long-term damage to his hip, we could no longer allow him to continue."

Boston have fallen into a 2-0 hole in the series after back-to-back blowout losses to Cleveland and faced an uphill battle on the road with or without their top performer.

Thomas was averaging 23.3 points and 6.7 assists per game in 15 postseason outings.
