MIAMI, Fl. (WRIC) — NFL star Odell Beckham Jr. was removed from an American Airlines flight Sunday after he began slipping in and out of consciousness, sparking concern for his health.

After the incident, Beckham took to Twitter, but did not address the specifics of the incident.

“Never in my life have I experienced what just happened to me,” he tweeted. “I’ve seen it all.”
