The 30 Rock star, who suffers from diabetes, was also treated for dehydration and was released after several hours in doctors' care.

However, Morgan was still too weak to perform and had to axe a show in the city that night, according to TMZ.com.

He was photographed catching a flight back to New York from Denver International Airport on Sunday (06May12), but had to rely on an assistant to push him through the airport in a wheelchair.

Morgan previously endured a health scare in January (12) after fainting during a party at the Sundance Film Festival in Utah. His representative blamed that incident on exhaustion and altitude sickness.
