Miami Heat forward Chris Bosh’s season — and potentially his career — could be determined over the next several days.

Bosh, 31, missed Sunday’s All-Star Game with a calf strain, but it was later determined that the injury was related to another blood-clot issue, according to several reports. Bosh missed the final 30 games last season after blood clots were found in his lungs.

The 11-time All-Star will meet with doctors Thursday to determine the course of treatment, Yahoo! Sports reported early Tuesday morning. He was prescribed blood thinners last year and took them for seven months. Doctors are often hesitant to allow a patient on such medications to engage in sports where there is physical contact.

Bosh’s agent, Henry Thomas, told The Miami Herald that it was “too soon” to say that Bosh definitely has another blood clot. The newspaper said that the blood clot was not life-threatening.

The Associated Press, citing a a person with knowledge of the situation, reported Tuesday that Bosh had resumed taking blood thinners to treat a blood clot in his leg with hopes that he can resume playing this season.

The person spoke to the AP on condition of anonymity because neither the team nor Bosh has revealed anything publicly.

Expert: Chris Bosh, like many, at risk of blood clot recurrence

Bosh is Miami's leading scorer at 19.1 points per game. He said over the weekend in Toronto — he also pulled out of the 3-point contest — that he was optimistic about playing again this season.

Bosh was shut down at the All-Star break last season because a blood clot had found its way to his lungs. Doctors believe it started with a calf injury.
