Bosh released a video statement Friday night that was accompanied by a Twitter post of, "Setbacks may happen, but my intentions remain the same. Thank you all for the warm wishes and support."
The Heat announced earlier Friday that the 11-time All-Star would not be allowed to participate in their preseason training camp after failing a physical and remaining unable to return to basketball activities.
"I had the intention of releasing Episode 2 of 'Uninterrupted: Bosh Rebuilt' today under the assumption I would be cleared to go for camp," Bosh said in his video post after his failed physical. "Unfortunately that is not the case. But that doesn't stop me from wanting to share my creative side with you guys and hoping that you want to come along on the journey with me. So, just because the journey has ups and downs doesn't mean that I will stop sharing with you guys. So I will just continue to share, despite what's going on.
"Little setbacks happen, but that doesn't change my intentions and what I want to accomplish. So, I hope you continue to watch. I hope you continue to really just take in my journey and just come along with me, with the ups and the downs. So it's a down moment right now, but everything's going to be all right."
The 32-year-old Bosh wants to resume playing even though each of his last two seasons was cut short by blood clots. He was examined by doctors in recent days in an attempt to be cleared for camp, which begins Tuesday.
Last week, Bosh repeated what he said during the 2016 playoffs when he declared himself ready to play in the upcoming NBA season.
Bosh, eight months removed from his second blood clot-related health scare in a calendar year, posted a video of a private workout last month.
If the medical issue keeps Bosh out of action for good, he would be paid the remainder of his contract -- three years, $76 million -- but that wouldn't count against the Heat's salary cap after Feb. 9. He averaged 19.1 points and 7.4 rebounds in 53 games last season when the second bout with clots began in February.
