Funnyman Tracy Morgan flew back to New York hooked up to an oxygen tank after losing consciousness at the Sundance Film Festival in Utah over the weekend (21-22Jan12).
The 30 Rock star was admitted to hospital after passing out at the Park City venue following his acceptance speech at the Creative Coalition Spotlight Awards.
He was treated for altitude sickness and exhaustion before being released and he flew back to New York on Monday (23Jan12) to resume filming on the hit TV show.
However, Morgan was taking no chances with his health and was photographed walking through the airport while hooked up to an oxygen tank. The star was sporting a tube attached to his nose, but was still able to joke with the waiting photographers.
In footage obtained by Tmz.com, the star is seen telling snappers, "Superman ran into a little Kryptonite today."
