Almost exactly one year ago, the Heat announced that Chris Bosh was going to miss the remainder of the 2014-15 NBA season due to blood clots that were found in his lungs. Doctors used blood thinners to get rid of the clots, but those blood thinners made it impossible for him to suit up for Miami. We talked with Bosh about his time away from the basketball court during an interview at the beginning of the 2015-16 NBA season, and he spoke about how the situation changed him.

Unfortunately, it sounds like Bosh might be dealing with a similar situation right now. Last Friday, Bosh was ruled out of the 2016 NBA All-Star Game with a strained left calf. It didn’t sound all that serious at the time, but yesterday, the Miami Herald revealed the Heat were worried the calf injury may have stemmed from blood clotting in his leg. Yahoo! Sports spoke with additional sources early this morning who confirmed that Bosh is scheduled to undergo a series of tests this week to determine whether or not he will need to use blood thinners again to clear up blood clotting. If he does, he could miss another extended period of time.

The Yahoo! Sports report points out that Miami officials are feeling more optimistic now than they were just a few days ago, but it’s unclear what impact Bosh’s latest injury will have on him moving forward. Stay tuned for further details.
