BOSTON (CBS) — The Celtics had little issue without Isaiah Thomas on Wednesday night against the Orlando Magic.

We’ll see if they can do it against Friday night when they host the Atlantic Division leading Toronto Raptors at the TD Garden.

Celtics president Danny Ainge joined 98.5 The Sports Hub’s Toucher & Rich for his weekly call into the show on Thursday, and said a groin injury will probably force Thomas to miss Friday’s game.

“It’s day to day. He had a PRP (platelet rich plasma) injection [Wednesday] into his thigh muscle. It’s just day to day,” said Ainge. “He’s a warrior and loves to play. He’ll be back faster than most players, but we really have to be careful with Isaiah for the long-haul.

“He probably won’t play tomorrow, and we’ll just try to get him as much rest as we can,” said Ainge.

Thomas suffered a pulled groin late in the first half of Monday night’s loss to the Houston Rockets, but went on to play 33 minutes and score 20 points in the defeat. He traveled with the team to Orlando, but flew back to Boston on Wednesday morning for treatment.
