Rory McIlroy held back by Shane Lowry in furious confrontation with USA caddie at Ryder Cup

Rory McIlroy had to be held back by Shane Lowry during a furious confrontation with Justin Thomas' caddie at the Ryder Cup.

Footage from outside Marco Simone shows McIlroy swearing and pointing at Jim Mackay, AKA Bones, before getting bundled into a car by Lowry.

There was late drama in Rome as Patrick Cantlay and Wyndham Clark claimed an unlikely point from McIlroy and Matt Fitzpatrick in the final four-ball match on Saturday.

Cantlay was mocked by European fans amid reports he is refusing to wear a USA hat as a protest over lack of pay at the Ryder Cup.

After a decisive putt on 18, Cantlay's caddie Joe LaCava mimicked the home crowd by waving his hat around.

McIlroy still had a putt to tie the match and appeared upset that LaCava, who is famous for being on Tiger Woods' bag for many years, was getting in the way of his routine.

Europe stars Lowry, Justin Rose and McIlroy's caddie Harry Diamond all confronted LaCava over his behaviour behind the 18th green.

Now, a video has shown McIlroy in a heated exchange with Thomas' caddie Bones, appearing to shout 'that's f***ing disgraceful'.

The Northern Irishman is good friends with Woods and Thomas, who the two caddies in question have worked for.

Speaking to the media as the video emerged, Europe captain Luke Donald confirmed McIlroy was upset with LaCava for stepping on his line.

Donald said: "Rory politely asked Joe to move aside. He was in his line.

"He stood there and didn’t move for a while and continued to wave his hat. So I think Rory was upset about that.”

USA staged a fightback on Saturday afternoon after a historic Friday thrashing and another bad morning.

Zach Johnson's men won the four-ball session 3-1 and pulled the event back to 10½-5½ after going 9½-2½ down.

Despite Cantlay's late heroics, the Americans still require the biggest comeback in Ryder Cup history on Sunday to retain the trophy.

Europe, meanwhile, need four points from the 12 singles matches.
