The “30 Rock” star, 43, was immediately taken to the Park City Medical Center after falling unconscious following his acceptance of the Spotlight Initiative Award, People magazine reported. The honor was presented to Morgan at an event hosted by the Creative Coalition.

Although both People and the Hollywood Reporter have cited sources at the dinner who say Morgan appeared to be inebriated, a spokesperson for the Medical Center said there was no evidence of drugs or alcohol in his system.

Morgan’s rep also denied in a statement that the actor had been drinking that evening, and said the actor was hospitalized “from a combination of exhaustion and altitude.”

“Any reports of Tracy consuming alcohol are 100% false,” the statement said.

The outspoken actor and “Saturday Night Live” veteran has diabetes and underwent a kidney transplant in 2010. In 2005 and again in 2006, he was arrested for drunken driving, incidents that he has said convinced him to sober up.

He is at Sundance to promote the film “Predisposed,” directed by screenwriter Ron Nyswaner, which premieres at the festival on Friday and co-stars Morgan, Jesse Eisenberg and Melissa Leo.
