Cleveland Cavaliers' J.R. Smith involved in altercation after game

March 5 (UPI) -- Cleveland Cavaliers guard J.R. Smith, who is out with a thumb injury, was involved in an altercation after a 120-92 loss to the Heat in Miami on Saturday.

Smith, in street clothes, had to be held back -- first by an assistant coach and then by a referee -- from fighting with Heat players, particularly Rodney McGruder and Dion Waiters.

Apparently, the Cavaliers were upset with the aftermath of a dunk by McGruder on Channing Frye.

"They took offense to something," Heat guard Tyler Johnson said. "But it was nothing."

Frye agreed.

"I guess there was some extracurricular," Frye said. "Tempers flared. It is what it is -- it's not really a story."

The teams play again Monday night in Cleveland.
