REPUBLIC of Ireland striker Kevin Doyle has been forced to retire at the age of just 34 because of “repeated headaches” from heading the ball.
The Co. Wexford native, who has been playing in the United States for Colorado Rapids since 2015, retired based on medical advice following a series of concussions.
The former Cork City, Reading and Wolves forward said heading the ball was becoming difficult because of the headaches that he would be would be left with.
Doyle explained he wanted "to avoid the possibility of these symptoms becoming more serious and permanent".
He added that he made the decision having suffered "numerous" concussions since he became a professional football in 2002.
"This year it has been clear to me that heading the ball was becoming problematic and causing me to have repeated headaches," he said.
"Two concussions this season and numerous others over the years have made this more concerning.
"I'm sad to announce that after listening to medical advice I will play no further part this season and will be retiring.
