Isaiah Thomas has a decision to make.

The Celtics guard met with a hip specialist Tuesday to determine whether surgery would be necessary to repair his injured hip. 

"His X-rays and all of the information that they gathered is being sent to another specialist," Celtics coach Brad Stevens told reporters prior to Tuesday's game in Cleveland. "I think he's probably going to collect one to two more opinions and then go from there before he ultimately makes a decision on the next step, whether that next step is surgery or a specific rehab program, whatever the case may be.

"But he's still obviously really sore... the last [doctor] said that some of the inflammation that he has has to go down before they can make the final call."

Thomas, who led the Celtics in scoring and assists, is out for the remainder of the playoffs because of the nagging hip injury he aggravated during Game 2 of the Eastern Conference finals. Even without Thomas, the Celtics avoided a 3-0 series hole by winning Game 3 in Cleveland. 

The Celtics held a 57-47 halftime lead on the Cavs in Tuesday's Game 4. Thomas did not make the trip to Cleveland, but the Celtics are hoping he can attend Thursday's Gamr 5 back in Boston.
