Cork born shot-stopper commits his future to the St Andrew's club by signing a new one-year contract
The Cork born shot-stopper has made one appearance for the Boys in Green and his new deal at St Andrew's means he will stretch his Blues career to an eleventh season.
Speaking to the club’s website, Doyle told of his delight at remaining in the Midlands.
"I love it here at Blues. It's a great club, a massive club," he said.
"I'm pleased to have re-signed and I'm really looking forward to getting back in on Monday and seeing the lads and the new management staff."
Doyle came through the Blues’ academy before penning his first professional contract in 2003.
He has made fifty appearances between the sticks but has had loan spells with Chester City, Nottingham Forest and Millwall during his time at St Andrew's.
The goalkeeper earned his sole Irish cap during the tour of America in 2007 when he started in a 1-1 draw with Ecuador. Doyle also has four U21 appearances to his name.
