UPDATE: Amy Roberts, a spokeswoman for Park City Medical Center, tells TMZ no drugs or alcohol were found in Tracy's system upon medical evaluation.

Morgan's rep, Lewis Kay, also released a statement saying, "From a combination of exhaustion and altitude, Tracy is seeking medical attention."

Kay adds, "He is with his fiance and grateful to the Park City Medical Center for their care. Any reports of Tracy consuming alcohol are 100% false."

Ugh, get well Tracy. You're a big old dumb head, but you're our big old dumb head. I was super angry when I read that it was alcohol related, but now it's confirmed that it wasn't. Either way, I just hope he takes it easy and gets better soon.

Blah. I hope he's okay...

same here, I hope it is nothing serious at all....
