PARK CITY, Utah (AP) -- Comedian and "30 Rock" cast member Tracy Morgan said he will be back at work Tuesday after being hospitalized while attending the Sundance Film Festival in Utah.
Morgan's publicist, Lewis Kay, said Monday that the actor suffered from exhaustion and altitude when he collapsed Sunday night in Park City, where the elevation is 7,000 feet.
Morgan posted a comment Monday on Twitter that the high altitude "shook up this kid from Brooklyn."
"Superman ran into a little kryptonite," he quipped.
He also said on Twitter that he would be back to work Tuesday on "30 Rock."
Ron Nyswaner, co-director of the Sundance film "Predisposed," in which the actor stars, said Morgan's collapse resulted from "altitude sickness combined with his diabetes. And he hadn't eaten. He hadn't had enough water."
Kay said hospital officials report no drugs or alcohol were found in Morgan's system.
Morgan had been attending an event for the Creative Coalition at which he had just received an award.
In "Predisposed," which stars Jesse Eisenberg and Melissa Leo, Morgan plays a drug dealer caught up in the push-and-pull between a piano prodigy and his troubled mother.
