Mario Chalmers will start at point guard for the Heat in place of Carlos Arroyo, according to coach Erik Spoelstra.
"It was a tough decision," Spoelstra said. "It wasn't anything that Carlos was doing wrong. He was doing everything that I asked him to do. I think this is what's best for the team right now."
Chalmers earned his second start of the season in the Heat's 120-103 win over Toronto on Saturday night.
Miami won't play until Thursday when they face the Knicks.
