MIAMI - Miami Heat forward Chris Bosh, sidelined for the remainder of the NBA season with blood clots in his lungs, could begin exercises this month but will not resume basketball activities until September.

The Heat provided the update on Monday after benching Bosh last month once his condition was diagnosed.

A statement from the Heat said doctors will re-evaluate him later this month and, with their approval, he can begin regular exercise and strength training next month.

The 30-year-old veteran averaged 21.1 points, 7.0 rebounds and 2.2 assists in 44 games for the Heat this season.

He returned to watch his team-mates on Monday.

"I'm making sure that I stay patient and not getting too ahead of myself," Bosh said of his recovery plans.

"I'm just happy to be back. It's not under the circumstances I'd like but beggars can't be choosers."

With 28 wins from 62 games, the Heat stood level with Charlotte and Indiana for the last two play-off positions in the Eastern Conference with 20 games remaining.
