Devin Booker was carried off the floor with a strained left adductor in the fourth quarter of Tuesday's loss.
Booker pulled up and appeared to clutch his groin area as he was coming back down the court.
"I've seen guys get carried off and play the next day and guys not," Jay Triano said. "I'll let the doctors figure out the severity of it. I'm sure they'll have to do an MRI or something to see and make sure we take care of him the right way."
Booker had scored 46 points in Monday's game.
