30 Rock actor Tracy Morgan is recovering following a collapse at the Sundance Film Festival. Morgan, 43, blamed the incident on the altitude of Park City, Utah, home to the annual star-studded festival, E! News reports.

"Superman ran into a little kryptonite. The high altitude in Utah shook up this kid from Brooklyn," Morgan tweeted Monday. Shortly after, Morgan, who is diabetic, tweeted his thanks to the hospital staff and said he would be back to work Tuesday shooting "30 Rock."

Morgan was being honored at the Creative Coalition Spotlight Awards when, after giving a speech, he was escorted outside — where he collapsed. Morgan was brought to Park City Medical Center. No drugs or alcohol were found in his system. Reps for the star attributed the incident to a "combination of exhaustion and altitude."
