Details are still sketchy at this point, but it appears the tragic life of TUF veteran Josh Samman has come to an end.

TMZ has the scoop:

UFC middleweight Josh Samman — who appeared on “The Ultimate Fighter” — has died after spending several days in a coma … this according to his ‘Ultimate Fighter’ castmate Gilbert Jamal Smith.

Samman was found unresponsive early Friday morning at an apartment in South Florida. His roommate, Troy Kirkingburg — a UFC announcer — was pronounced dead at the scene.

It’s unclear how the two men died.

There were rumblings that heroin played a role — but Samman’s mother came out and said doctors found no traces of the drug in his system. There were also no signs of foul play according to reports.

Samman was 28.
