Miami Heat forward Chris Bosh missed Sunday’s All-Star Game with a calf strain, but it was later determined that the injury was related to a blood-clot issue, according to several reports.

Bosh, 31, missed the final 30 games last season after blood clots were found in his lungs, according to USA Today.

The 11-time All-Star will meet with doctors later this week to determine treatment, Yahoo! Sports reports. He was prescribed blood thinners last year for seven months.

Bosh’s agent, Henry Thomas, told The Miami Herald that it was “too soon” to say that Bosh definitely has another blood clot.

The Associated Press 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.
