Heat All-Star forward Chris Bosh will not accompany the team to Atlanta for Friday’s game against the Hawks as he deals with an issue with his calf.

The Heat made the announcement Wednesday and added only “When further information is available that we can pass along, it will be provided.”

Bosh was named an Eastern Conference All-Star reserve, his 11th trip to the game, but abruptly pulled out on Thursday while in Toronto. The injury was described as a calf strain. Bosh remained in the city for the weekend events but was replaced in the game by Hawks center Al Horford. Bosh was also to participate in the 3-point contest.

There are reports that Bosh is experiencing blood clots and has been put on blood thinners. Bosh was hospitalized for nine days during the 2015 All-Star break to treat blood clots in his lung. He was placed on blood thinners and missed the Heat’s final 30 games of the season.

Bosh, who played at Georgia Tech, is the Heat’s leading scorer at 19.1 points per game.

The Heat will also be without center Hassan Whiteside, who was suspended for one game for an elbow he threw against eh Spurs before the break.
