Comic Tracy Morgan has been taken to hospital after he fainted during an awards ceremony at the Sundance Film Festival on Sunday.
The 30 Rock star was honoured at the Creative Coalition Spotlight Awards in Park City, Utah and reportedly fell unconscious outside the venue after giving his acceptance speech, according to TMZ.com.
An ambulance took the star to a nearby hospital for treatment and he was joined by his fiancee Megan Wollover.
The comedian's representative Lewis Kay has put the incident down to exhaustion and altitude sickness and dismissed reports which suggested the star had been drinking.
Kay says, "From a combination of exhaustion and altitude, Tracy is seeking medical attention... He is with his fiance and grateful to the Park City Medical Center for their care. Any reports of Tracy consuming alcohol are 100 per cent false."
Morgan, who suffers from diabetes, underwent a kidney transplant in late 2010.
