Tracy Morgan of "30 Rock" is going to be fine, according to the actor's tweets, after he collapsed in Park City Sunday.

Apparently, the thin air got to him, he said.

"Superman ran into a little kryptonite," he tweeted. "The high altitude in Utah shook up this kid from Brooklyn."

Morgan said he'll be out of the hospital (and he gave a shout to the fine staff at Park City Medical Center) and back in Los Angeles shooting his TV show by tomorrow. Good to see him back on his feet and know that it was only the thin air that did him in for a bit.

But celebs from sea-level Hollywood beware: Utah isn't for wusses.
