Colorado Rapids forward Kevin Doyle says he is retiring from professional football because of repeated concussions.
Doyle is from Ireland and has played 16 years both in Europe and in Major League Soccer. He released a statement via social media on Thursday.
"This year it has been clear to me that heading the ball was becoming problematic and causing me to have repeated headaches," Doyle wrote. "Two concussions this season and numerous other over the years have made this more concerning."
