ESPN is currently reporting that Miami Heat Forward Chris Bosh is expecting to return to the NBA for the 2016-17 season, and is currently training for this said return.
Bosh wanted to return during this past post season, when the Heat had a chance to reach the Eastern Conference Finals, and go up against their former teammate LeBron James. Bosh found an independent doctor that evaluated his case, and in the end cleared him to return back to action. However, the Heat rejected this, so in reality we will not see Chris Bosh back with the Heat until Heat doctors clear him.
Bosh is training as if he expects the Heat to clear him, so that can be looked at as a sign of good news.
