Former Republic of Ireland international Kevin Doyle has announced his retirement following medical advice.
Doyle, who enjoyed spells with Reading, Wolves, QPR and Crystal Palace, called time on his career after suffering a number of concussions this season with his current side Colorado Rapids.
The 34-year-old explained his decision to retire in a statement on Twitter on Thursday night.
Doyle wrote: "Today I'm sad to announce that after listening to medical advice I will be playing no further part in this season and will be retiring.
"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.
"After consulting the experts in this field, it has been decided that to avoid the possibility of these symptoms becoming more serious and permanent, I will be hanging my boots up for good."
Doyle began his career with Irish club Cork City before moving to Reading as a youngster in 2005.
He went on to score 56 goals in 163 appearances for the Royals before joining Wolves, where he enjoyed six successful seasons.
Doyle moved on to MLS side Colorado Rapids in 2015 after falling out of favour at Molineux, and made 78 appearances for the club before announcing his retirement.
The Irishman also won 64 caps for his country over an 11-year period, scoring 14 times.
"I'm privileged and proud to have fulfilled my childhood dream of playing for my country," added Doyle. "Everything else was a bonus."
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."
