“As some of you may have heard, I passed out during the first performance of COCK last night,” Egerton wrote in a statement posted on the Instagram Story portion of his verified Instagram account. “I am completely fine. Slightly sore neck and a bruised ego but I am fine.”

Egerton joked about putting a “positive spin” on the incident and wrote that he would appreciate that anyone who attended the performance would just say that he gave “such a committed, electrified performance” that his “body couldn’t handle it and checked out.”
