During last night's closing Dublin leg, McGraw reportedly collapsed at around 10:37pm following a performance of his hit Humble & Kind.
Faith Hill, McGraw's wife and recording partner, spoke to the crowd saying that she had chose to end the performance.
[quote]"He's been super dehydrated". "I apologize, but I made the decision that he can not come back out on stage".
McGraw was performing at the 3Arena on the final night of the Country to Country festival, a three-day event featuring a host of country music stars that also incorporated performances in London and Glasgow on Friday and Saturday night.
Meanwhile, a rep for the singer said that he had been attended to on-site by local medics and is expected to be "fine'". News, eyewitnesses revealed that numerous crew members rushed McGraw off the stage once he'd collapsed: "The crowd was really anxious, like, 'What just happened?'" whereas Hill "didn't seem that anxious or distracted". He looked to be in good health as he walked behind wife Hill, who sported a black raincoat over a black turtleneck and jeans.
The country music superstar was unable to continue the performance in Dublin.
A representative for McGraw said that the artist "will be fine". Faith Hill then encouraged everyone to drink water and stay healthy.
Following the announcement, fans began chanting, "Get well, Tim!" "Whether I want to do it continually, whether I want to stop doing it, any of those things, it's my saviour in a lot of ways".
"Anything that's ever happened good in my life has come from music", McGraw said.
