Four of the biggest stars in world golf - who sit on either side of the split between the PGA Tour and LIV Golf that has fractured the sport in recent years - will compete against each other in a made-for-TV event in December.

McIlroy and Scheffler will be representing the PGA Tour with American pair DeChambeau and Koepka competing on behalf of the Saudi-backed LIV Golf.

Negotiations between the PGA Tour and Saudi Arabia's Public Investment Fund (PIF) have been going on for over a year as the two parties seek to end the split in the sport.

The quartet are expected to earn significant appearance fees and a charitable element to the event is likely to be included.

McIlroy told Golfweek: "I’m thrilled to partner with Scottie in what promises to be an exciting duel against Bryson and Brooks in Vegas this December.

"This isn’t just a contest between some of golf’s major champions, it’s an event designed to energise the fans. We’re all here to put on a great show and contribute to a goodwill event that brings the best together again."

The news comes after McIlroy confirmed that he would be cutting down on the number of tournaments he plays next year after "hitting a wall" following his painful loss at the US Open in June.

The four-time major champion said: "I’m going to just have to think about trying to build in a few extra breaks here and there next year and going forward because I felt like I hit a bit of a wall sort of post-US Open, and still feel a little bit of that hangover.

"27 [is too many tournaments]. I’m usually sort of like a 22 sort of person. But again, that was when I was sort of in my 20s and didn’t have the responsibilities that I do now.

"I’m going to try to cut it back to like 18 or 20 a year going forward, I think."
