Country singer Tim McGraw collapsed on stage during a performance in Ireland on Sunday, Rolling Stone reports .
McGraw, 50, reportedly dropped to his knees after finishing a song and sat down.
McGraw's wife, singer Faith Hill, later addressed the crowd and explained that he was suffering from dehydration.
McGraw was performing at the Country to Country Music Festival in Dublin, a multiple day festival that features sets in various locations throughout the United Kingdom.
"He's been super dehydrated," Hill said to the crowd, according to social media posts. "I apologize. I made the decision that he cannot come back out.
