What story do you? The latest on Chris bosh. Bosh has two NBA titles but now life-threatening illness is putting his career in jeopardy and last night he made his first public appearance since being diagnosed with blood clots in his lungs and Matt Gutman sat down with him for the exclusive interview. It was the kind of welcome that the Miami heat's Chris bosh is used to. Blocked by bosh! Game over. Reporter: But this one was merely for surviving. I want to thank each and every one of you for all the love. Reporter: The ten-time all-star making a surprise appearance last night two weeks since he was grounded by a life-threatening condition, blood clots in his lungs. I'm not out of the woods. Reporter: Now speaking about it for the first time emotionally to ABC news. It's a tough pill to swallow. Reporter: For weeks the former member of the Miami heat storied big three which included Lebron James and dwyane wade had fought through the pain. Myself, my wife all went to Haiti. I suffered for two days and the third day we came back and I went to the doctor's office. Finally he checked himself into the hospital. I remember looking at the doctors and more people start coming in. Reporter: That's never good news. The clots traveled from his calf to his lungs. It's a condition that kills 100,000 Americans every year. Often people with poor circulation like the elderly or the very tall. The same condition that a day earlier had killed former NBA star Jerome kersey. That's some things you start getting spooky for me. Reporter: The doctor saved his life but perhaps not his career. Let's hope you make it back next season. I will. But if you don't have you thought about what's next? I just kind of think of things I can get better at, to kind of help that process when I'm done. Reporter: These days he's homebound with his wife and three kids playing a different game. But primed for that bigger arena. For "Good morning America," Matt Gutman, ABC news, Miami. Well, bosh obviously had the right attitude. Now, outlook is good for him. He's expected to resume full basketball activity this September. It could be ready for the start of the next season. Right attitude about it. Sure does. Don't count him out. He is so tenacious. But what a beautiful family. Oh, yeah. Good luck to him.
