TOMMY FLEETWOOD has had to apologise following the X-rated joke he made about Luke Donald live on BBC radio.

The world number 14 forgot he was on national radio when he aimed a jibe at his Ryder Cup captain.

Fleetwood has been selected as one of Donald’s Captain’s Picks for the highly anticipated Ryder Cup later this month.

But it didn’t stop him making a joke about his long-term friend when asked on air what kind of captain he would make on Radio 5 Live.

Fleetwood simply replied “S**t” before immediately realising he had made a mistake and issuing an almost instantaneous apology.

He said: “Sorry, sorry, I lost track of where I am. I take that back.”

The comment was clearly meant as a joke with Fleetwood and Donald known to be close friends.

The 32-year-old went on to gush about his mate, saying: “Luke will be amazing. He’s somebody I am very close to.

“He’s a calm figure, a confident figure, he’s handled the biggest moments in the sport unbelievable well.

“To have someone leading from the front like that has been great. He’s definitely brought his personality to the captaincy.

“I do feel very honoured, as a friend as well but to play under a European legend, I am looking forward to experiencing his captaincy.”

Fleetwood has been joined by Ludvig Aberg, Nicolai Hojgaard, Shane Lowry, Justin Rose and Sepp Straka as the Captain’s Picks for the Ryder Cup.

Whilst Matt Fitzpatrick, Tyrrell Hatton, Viktor Hovland, Robert MacIntyre, Rory McIlroy, and Jon Rahm all qualified for the match-up against the United States automatically.

The Ryder Cup kicks off on September 29 in Rome with Europe hoping to snatch the trophy back off the US who won the delayed 2020 competition.
