McIlroy admits he almost quit the DP World Tour over one rule.

Rory McIlroy has revealed he came within a single conversation of giving up his European Tour membership in 2019 — a move that would have permanently barred him from ever captaining or vice-captaining a European Ryder Cup team.

The six-time major champion admitted the near-mistake while speaking to reporters ahead of this week's Abu Dhabi Championship at Yas Links.

McIlroy said he was seriously considering resigning his membership with what was then called the European Tour, now the DP World Tour, to focus entirely on the PGA Tour.

He felt he was spreading himself too thin by maintaining commitments on both sides of the Atlantic.

But one phone call with Keith Pelley, the former chief executive of the European Tour, changed everything.

"Yeah, I nearly fell foul of that rule," McIlroy said.

"I was going to give my DP World Tour membership up in 2019, and I had a chat with Keith Pelley at the time, and said, 'Look, you know, based in America. I want to focus over there for a bit.'"

Pelley's response stopped McIlroy cold.

"Keith said to me, 'Totally fine but you do know if you give up your membership or you resign your membership, you can't be a captain or vice-captain of the Ryder Cup in the future.'"

McIlroy's answer was immediate.

"I was like, 'Well, I'm not going to do that then.'"

The rule in question is a standing DP World Tour regulation.

Any player who resigns their membership forfeits the right to serve as a Ryder Cup captain or vice-captain for Europe in the future.

It is a restriction that applies regardless of the reason for leaving — whether for LIV Golf, the PGA Tour, or any other circuit.

McIlroy emphasized that his own thought process in 2019 had nothing to do with LIV Golf, which did not launch until 2022.

"I've had that, I guess, thought in my mind at one point as well, and it wasn't even about LIV," he said.

"It was just about feeling like maybe I was spread too thin and trying to play here, there and everywhere."

He added that the rule is well known across the tour.

"But everyone knows that rule, and everyone knows that if you abdicate your membership, that's the consequence."

The revelation carries heavy implications for a group of LIV Golf defectors who did resign their DP World Tour memberships.

Sergio Garcia, Lee Westwood, Ian Poulter and Graeme McDowell all terminated their memberships after joining the Saudi-backed breakaway league.

Garcia has since left LIV Golf and is preparing to return to the DP World Tour in 2027.

He confirmed last week that he would do everything possible to play well enough to earn selection for Luke Donald's next European Ryder Cup team at Adare Manor next September.

The Spaniard also expressed his willingness to help the team in any capacity.

Garcia remains the all-time record points scorer in Ryder Cup history.

He has made no secret of his desire to return to the team for the first time since 2021.

But becoming a future captain or vice-captain is an entirely different question.

Under the current DP World Tour regulations, players who have resigned their membership face restrictions on future Ryder Cup leadership positions.

That means Garcia, despite his legendary record, could find himself unable to follow in the footsteps of former European captains such as Bernhard Langer, Colin Montgomerie and Thomas Bjorn.

The same restriction applies to Westwood, Poulter and McDowell.

None of those players have yet commented publicly on whether the rule would affect any future captaincy ambitions they might hold.

The situation creates a stark contrast with McIlroy, who narrowly avoided the same fate through that single conversation with Pelley.

McIlroy's near-miss is a reminder of how easily the careers of even the biggest stars can be reshaped by a procedural rule.

If McIlroy had resigned in 2019, Europe would have lost one of its most prominent potential future captains.

Instead, McIlroy remains an active DP World Tour member and a likely candidate for Ryder Cup captaincy later in his career.

The DP World Tour changed its name from the European Tour in 2022, but the membership rule has remained consistent throughout.

McIlroy's story also highlights the personal calculation that every top player must make when deciding where to compete.

The demands of playing on both the PGA Tour and the DP World Tour are significant.

Travel between continents, different time zones, and overlapping schedules create a constant pressure on players to choose.

McIlroy based in the United States, felt that pressure acutely in 2019.

He was not the first player to consider giving up his European membership, and he will not be the last.

But the Ryder Cup captaincy restriction is a powerful disincentive for any player with aspirations of leading Europe's team.

For the LIV Golf defectors, the decision to resign their DP World Tour memberships was made with full knowledge of the consequences.

Whether any of them expected those consequences to matter is a separate question.
