Tracy Morgan Rushed to Hospital After Falling Unconscious at Sundance [Update]

Tracy Morgan
was rushed to a hospital moments ago at the Sundance Film Festival -- after the actor  fell unconscious at an award ceremony ... TMZ has learned.

Tracy was being honored at the Creative Coalition Spotlight Awards in Park City, Utah -- and sources tell TMZ, he appeared extremely intoxicated during his award acceptance speech.

We're told Tracy was escorted out of the building soon after his speech -- and fell unconscious outside the building.

Law enforcement sources tell us,  an ambulance was then dispatched to Tracy's location.

We're told Tracy was picked up and rushed to a nearby hospital for treatment. Calls to Tracy's rep were not immediately returned.

Amy Roberts, a spokeswoman for Park City Medical Center, tells TMZ no drugs or alcohol were found in Tracy's system upon medical evaluation.

Morgan's rep, Lewis Kay, also released a statement saying, "From a combination of exhaustion and altitude, Tracy is seeking medical attention."

Kay adds, "He is with his fiancée and grateful to the Park City Medical Center for their care. Any reports of Tracy consuming alcohol are 100% false."

9:50 AM PT: Tracy just tweeted, claiming the high altitude was responsible for his 911 emergency last night -- "Superman ran into a little kryptonite. The high altitude in Utah shook up this kid from Brooklyn."
