PARK CITY, Utah (AP) -- Comedian and "30 Rock" cast member Tracy Morgan says he'll be back at work Tuesday after being hospitalized while attending the Sundance Film Festival in Utah.
Morgan's publicist, Lewis Kay, says the actor suffered from exhaustion and altitude when he collapsed Sunday in Park City, where the elevation is 7,000 feet.
Morgan posted Monday on Twitter that the high altitude "shook up this kid from Brooklyn."
Kay says hospital officials report no drugs or alcohol were found in Morgan's system.
Morgan attended Sundance in connection with the comedy film "Predisposed," one of the 100 films at the festival, in which he plays a drug dealer named Sprinkles.
