Celtics-Heat: Chris Bosh participates in on-court workout

According to multiple reports, injured Miami Heat forward Chris Bosh took part in light, on-court workouts a day ahead of the team's Eastern Conference finals series against the Boston Celtics.

ESPN.com's Michael Wallace reports that Bosh "was observed going through an on-court workout at AmericanAirlines Arena late Sunday afternoon." Ira Winderman, the Heat beat writer for the Sun Sentinel, also reported shortly after on Twitter of Bosh's workout.

Bosh has been out since May 13, when he suffered a strain in an abdominal muscle during Game 1 of the Heat's series against the Indiana Pacers. The Heat eventually prevailed over a tough challenge from the Pacers, winning the series 4-2.

But head coach Erik Spoelstra told reporters that he was going into the series as if Bosh would not be available. Bosh's official diagnosis remains as out "indefinitely."

Pat Riley, the Heat's team president, also reportedly attended Bosh's on-court workouts.

Earlier on Sunday, Spoelstra gave no indication that Bosh would be a factor anytime soon, Wallace reported.

"I'm not even preparing for that right now," Spoelstra said earlier Sunday when asked about Bosh's status for the series. "I'm preparing for who we have in the gym. So our focus is (Monday). And that's all I can concentrate on. We have enough to win (Monday). That's all that any of our guys should be focused on."
