LONDON, United Kingdom (AFP) — Rory McIlroy said the European side will have to "rewrite the rules" for Ryder Cup eligibility after Spain's reigning Masters champion Jon Rahm jumped ship to LIV Golf.

Saudi-backed LIV pulled off a coup Thursday when Rahm confirmed weeks of speculation by announcing he was joining the circuit in a deal reportedly worth hundreds of millions of dollars.

Ian Poulter, Lee Westwood and Sergio Garcia have all been declared ineligible to play for Europe at the Ryder Cup after signing for LIV.

Henrik Stenson was removed as captain.

World No. 2 McIlroy, a fierce and outspoken opponent of LIV, said Rahm following the other players to LIV would require the DP World Tour — formerly the European Tour — to rethink its stance.

Rahm is a mainstay of the European team and helped it win the Ryder Cup this year.

The next Ryder Cup is in Bethpage, New York.

"Jon is going to be in Bethpage in 2025," Northern Ireland's McIlroy told Sky Sports on Thursday, after Rahm's move to LIV was confirmed.

"So because of this decision, the European Tour are going to have to rewrite the rules for Ryder Cup eligibility."

"There's absolutely no question about that — I certainly want Jon Rahm on the next Ryder Cup team."
