Miami Heat star Chris Bosh, who missed the second half of each of the past two NBA seasons because of blood clots, failed a pre-season physical and can't return to action, the team said Friday. "The Miami Heat and Chris Bosh, in consultation with team doctors and other physicians, have been working together for many months with the mutual goal of having Chris return to the court as soon as possible," the Heat said in a statement. The Heat said privacy rules prevented them from further comment.
