Hassan Whiteside was wearing a walking boot and a knee brace on Sunday. Whiteside has been ruled out for Game 4 on Monday.

Whiteside is listed as day-to-day with a sprained MCL.

Erik Spoelstra said “it’s way too early to tell” how long Whiteside will be out.

“Where my mind was, where Hassan’s mind was, that’s about the best news we could have,” Spoelstra said of the MRI showing a sprain and not a tear. “He’s going to be doing treatment, a lot of rest.”

Whiteside will be a free agent this offseason and has been poised to sign his first significant NBA contract.
