Henrik Stenson with his Ryder Cup captain replacement Luke Donald

Henrik Stenson and Paul Casey are reportedly among the latest stars set to resign from the DP World Tour — taking the total of high-profile LIV Golf players either having already walked away from the old European Tour or about to in the immediate future to nine.

Last week, four long-standing members — Sergio Garcia, Lee Westwood, Richard Bland and Ian Poulter — quit the circuit with the threat of incremental fines of up to $630,000 for DP World Tour card holders who continue to participate on the LIV Golf Circuit.

Now The Telegraph has reported that Swede Stenson, England’s Casey, Germany’s Martin Kaymer, and South African duo Charl Schwartzel and Brandon Grace are set to follow suit.

Paul Casey

All DP World Tour members who have competed on LIV Golf since its inaugural event in London last June are in breach of the tour’s tournament release regulation and so are liable to the sanctions imposed on members in breach of that rule.

Following the DP World Tour’s fine and suspension of 17 members who moved to the new circuit last June for the inaugural LIV Golf event in London, a group of players led by Adrian Otaegui, Poulter and Justin Harding filed an appeal against the DP World Tour. The LIV members were granted an injunction to enter the Genesis Scottish Open, pending a full hearing before the arbitration panel in February, which voted in favour of the DP World Tour.

The move to quit the DP World Tour means LIV Golfers will not face any more fines in the future for continuing to compete on the new series.

Martin Kaymer

However, it also rules out any future Ryder Cup participation for the European contingent, with Stenson — who was stripped of the Team Europe captaincy after he switched — Kaymer and Casey all having featured prominently in the biennial tournament along with Poulter, Garcia and Westwood.

New Ryder Cup skipper Luke Donald recently admitting his sadness at the departure of the initial trio of Westwood, Poulter and Garcia. “It is a shame,” he said. “They’ve got a lot of history when it comes to the Ryder Cup. Ultimately this is their choice and I wish them well.”

Rory McIlroy, a Ryder Cup teammate of all the European players, echoed that sentiment: saying: “I think it’s a shame that you’ve got the highest points score ever in the Ryder Cup [Garcia] and two guys that, when they look back on their career, that’s probably going to be at least a big chunk of their legacy is the roles that they have played in the Ryder Cup for Europe [Westwood and Poulter] … But at the end of the day that was their choice.”
