Tracy Morgan collapsed last night at the Sundance Film Festival in Park City, Utah.  But the actor/comedian's reps and medical spokespeople confirmed that drugs and alcohol were not the cause. 

Deets inside...

Reportedly, Tracy's diabetic history mixed with the high altitude are the likely culprits for his scary collapse yesterday. 

TMZ reports that while he was being honored at the Creative Coalition Spotlight Awards, the "30 Rock" star's behavior appeared intoxicated and barely together.  And he fell unconscious once outside of the building.  He was rushed to a nearby hospital with his fiance' by his side.

But these are also symptoms of exhaustion and high altitude.  A medical spokeswoman confirmed that there were no alcohol or drugs in his system.

Morgan's rep also released a statement saying, "From a combination of exhaustion and altitude, Tracy is seeking medical attention.  He is with his fiance and grateful to the Park City Medical Center for their care. Any reports of Tracy consuming alcohol are 100% false."

Tracy went through a kidney transplant over a year ago after his Diabetes 2 situation (which he had suffered with for over 15 years) took a toll on his body.  He's changed his living habits to a more healthy lifestyle since.
