One of the stars of the NBC comedy "30 Rock" was rushed to the hospital in Denver over the weekend after suffering flu-like symptoms, reports TMZ.com.

Tracy Morgan was scheduled to perform at a comedy show Saturday night, but had to cancel due to the medical problem earlier in the day, the story says. He was treated at the hospital for several hours and released.

Morgan has fallen ill before at high altitude, being hospitalized in January after falling unconscious at the Sundance Film Festival in Utah, the piece notes.
