Chris Bosh is the star and the director of the new Uninterrupted original series Rebuilt, and in the first episode of the series he talks at length about the blood clots that very nearly ended his career. As Bosh explains in the episode, the blood clots would have ended his career if he had taken the legal advice that he was given during his second bout with blood clots in February 2016.

After dealing with a blood clot in his lung in February 2015 and missing the remainder of the 2014-15 NBA season as a result of it, Bosh worked his way back into the Heat lineup during the 2015-16 NBA season. But he was eventually diagnosed with more blood clots right before the 2016 NBA All-Star break, and it was at that time that Bosh’s doctors told him he would probably never play basketball again. His response? Well, let’s just say that he wasn’t prepared to accept what the doctors told him.

"Seeing the team doctors, they told me that my season’s over, my career is probably over, and yeah, this just happens. This is just how it is," Bosh said on Rebuilt. "I felt right away that I was written off. It was so just [wipes hands clean]. You know, put it to the side and matter of factly. If a doctor tells me, 'Hey, that’s it and this is how it is,' and I don’t buy that, I think that I have the right to disagree with you. I know inside me I have a lot of talent and a lot of ability, and I have it. I know I have it. It wasn’t a matter of if I’m going to play again, it’s when. So we took the bull by the horns."

The episode ends after he says those words, so it’s safe to say Episode 2 will likely start off with Bosh talking about how he was able to overcome the diagnosis he was given. In the meantime, you can watch Episode 1 here.

It’s still sort of unclear where Bosh stands today and whether he’ll definitely be able to get back on the court during the upcoming season. But Rebuilt will give you a better idea of what he’s had to endure just to get to the point where the idea of playing basketball again doesn’t seem so crazy.
