Kevin Doyle has announced his retirement from football om media advice, amidst concerns over the long-term effects of concussion.
The former Republic of Ireland striker cited “repeated headaches” for the decision.
The Wexford man, 34, announced the news on his Twitter page.
“I will play no further part this season and will be retiring,” he said.
“This year it has been clear to me that heading the ball was becoming problematic and causing me to have repeated headaches.
“Two concussions this season and numerous others over the years have made this more concerning.”
Doyle played 63 times for Ireland and scored 14 goals, and played a key role in Ireland’s Euro 2012 qualifying campaign under Giovanni Trapattoni.
He was named as the Ireland’s Player of the Year in 2010.

The former Wolves and Reading front man moved to Colorado Rapids two years ago.
He added: “After consulting the experts in the field, it has been decided that to avoid the possibility of these symptoms becoming more serious and permanent, I will be hanging up my boots for good.”
Doyle started his career in the League of Ireland with St Patrick’s Athletic before moving to Cork City. After two years with the Leesiders he moved to Reading in 2005 and spent four years at the club.
Doyle last lined out for the Rapids on 3 September.
Ireland manager Martin O’Neill, said: “I am disappointed to hear that Kevin has had to retire from football.
“Kevin was extremely popular with all of the players in the Irish camp and he was an excellent professional, who has served his clubs and country very well during his career.”
A former underage international, Doyle made his senior debut against Sweden in 2006 and had the honour of leading his country out as captain in the 1-0 friendly win over South Africa in Thomond Park in September 2009.
The former QPR and Crystal Palace frontman was part of the squad that won the Carling Nations Cup in 2011 and featured in two games at Euro 2012.
Doyle’s final appearance in a green jersey was the narrow defeat to Iceland last March in Aviva Stadium. He is joint 21st in the all-time appearance charts and joint sixth in the all-time goalscoring charts.
