Tim McGraw Collapses on Stage During Concert in Ireland

McGraw's wife, Faith Hill, told the audience that the incident was due to dehydration.

Tim McGraw collapsed on stage during a performance in Dublin, Ireland, on Sunday night.

The 50-year-old country singer had just concluded singing his single "Humble & Kind" at the Country to Country festival when he unexpectedly dropped to his knees before sitting down, Rolling Stone reported.

"Tim McGraw was suffering from dehydration in Dublin this evening at the C2C show," a rep for the star tells ET in a statement.

"He was attended to by local medical staff on-site and will be fine. He and Faith thank everyone for their love and support and look forward to seeing their Irish fans again soon."

The concert was halted as McGraw received medical attention backstage. 

His wife, country singer Faith Hill, addressed the audience alongside the members of McGraw's band, and explained that the musician has been "super dehydrated," and that his performance could not continue.

"I apologize, but I made the decision that he cannot come back out onstage," Hill said in a video from an attendee on Instagram.

An eyewitness at the concert tells ET, “After singing 'Humble & Kind,' [McGraw] kind of knelt down, as if to take in the reaction, then went and sat down on the stage behind, then got up and this was semi-darkness when he stumbled and fell forward to the left side of the stage. He was helped up to his feet by a couple of people from backstage who ran out quickly and then by the band as well, and hurried off stage!"

"[Hill] didn't seem that worried or distracted when she came back out [with] the band," the eyewitness adds. "She sang a couple lines of a gospel song ...  and that was it -- concert was cut short!"

McGraw previously performed on Friday in London, as part of the C2C festival's three-day multi-city tour.

The "Rest of Our Life" singer isn't scheduled to perform in concert again until May 31, during the Soul2Soul tour in Richmond, Virginia, alongside his wife.
