Tracy Morgan: back in good health and on Twitter. (Phil McCarten/Reuters)

Tracy Morgan is apparently doing just fine following his collapse last night during a Sundance Film Festival event.

He further explained the cause of his sudden hospitalization in Park City, Utah, the way all celebrities clarify their illnesses and announce their recoveries: on Twitter.

“Superman ran into a little kryptonite,” he wrote earlier this afternoon. “The high altitude in Utah shook up this kid from Brooklyn.”

Indeed, to Morgan’s tweet, a spokesman for the Park City Medical Center previously confirmed that no drugs or alcohol were found in the “30 Rock” star’s system following his collapse; Morgan’s rep also released a statement attributing the incident to “a combination of exhaustion and altitude.”

Morgan being Morgan, he had a couple more things to tweet about this matter.

“Thank U 2 the hospital staff,” he said. “Back at work 2morrow shooting 30 Rock. Holla at me!”

He then closed (for now) by tweeting: “Gotta thank the AMAZING medical staff and all my supporters! Love you. #GOgiants @Giants #ALL IN”

So in conclusion, Morgan is definitely back to his old self. The repetitiveness of his tweets and the non-sequitur comments regarding the Super Bowl-bound New York Giants provide definite proof.
