Golfing star Rory McIlroy had a fan removed from Hazeltine Golf Course after he shouted abusive and vulgar comments at him during a heated Ryder Cup battle.
Between the seventh and eighth holes, a fan yelled an obscenity at McIlroy and made references to his separation from Caroline Wozniacki.
McIlroy then confronted the heckler and, after pointing him out to a marshal, the fan was removed from the course in Chaska, Minnesota.
"Someone just said a few derogatory things I thought were over the line," McIlroy said.
"It is golf at the end of the day. You try to keep your utmost for who you are playing and for who you are supporting.
"That particular guy, who is obviously in a very, very, very small minority, just took it a bit too far. It's a tough environment, but we expect that.
"You have to keep your concentration out there and it's been a long day and sometimes emotions run high."
The PGA issued a statement saying security staff will remove any fans that "are disruptive in any way, including the use of vulgar or profane language directed at the players".
McIlroy has been heckled throughout the Ryder Cup, with some fans singing the song 'Sweet Caroline' by Neil Diamond. The Co. Down golfer responded by singing the words back at them.
Galleries of more than 50,000 have packed the course to cheer on the golfers.
