Chris Bosh’s season could be in jeopardy as he undergoes tests and evaluation to determine the seriousness of a blood clot in his left calf.

A Yahoo report states that there’s “more optimism in Miami on Monday than during All-Star weekend,” but the team is concerned that Bosh might be dealing with an issue similar to that which ended his 2014-15 season.

The Miami Herald reports that there’s no indication that the blood clots had traveled to his lungs, as was the case last year.

More details from Woj of The Vertical:

Miami Heat All-Star forward Chris Bosh is expected to meet with doctors Thursday to determine the seriousness of blood-clotting fears in his left calf and whether the use of blood thinners could allow him to return this season, league sources told The Vertical.

 

Bosh, an 11-time All-Star, met with Heat physicians on Monday in Miami and will get further evaluation on Thursday, sources said. There was more optimism in Miami on Monday than during All-Star weekend in Toronto that Bosh’s condition could be manageable, league sources said.

 

Bosh pulled out of the All-Star Game and 3-point contest on Friday because of the concerns of a potential blood clot. There was initially some apprehension about Bosh flying back to South Florida, but he did so without a physical problem.
