The PGA Tour has suspended the 17 members who are competing in the inaugural LIV Golf International Series event, it announced Thursday.

Players who resigned their membership before starting the LIV Golf event being held outside London that began Thursday are also no longer eligible to compete in tour events or the Presidents Cup.

"These players have made their choice for their own financial-based reasons," PGA Tour commissioner Jay Monahan wrote in a memo to the tour's membership. "But they can't demand the same PGA TOUR membership benefits, considerations, opportunities and platform as you. That expectation disrespects you, our fans and our partners. You have made a different choice, which is to abide by the Tournament Regulations you agreed to when you accomplished the dream of earning a PGA TOUR card and -- more importantly -- to compete as part of the preeminent organization in the world of professional golf."

The memo said players who compete in LIV events are ineligible to participate on the PGA Tour or any other tours it sanctions, including the Korn Ferry Tour, PGA Tour Champions, PGA Tour Canada and PGA Tour Latinoamerica.

LIV Golf, in a statement, called the PGA Tour's punishment "vindictive" and said it "deepens the divide between the Tour and its members."

Among them were six-time major champion Phil Mickelson, two-time major champion Dustin Johnson and longtime Ryder Cup participants Ian Poulter, Lee Westwood and Sergio Garcia.

Two other past major winners, 2020 U.S. Open champion Bryson DeChambeau and 2018 Masters champion Patrick Reed, have also reached agreements with LIV Golf to compete in future tournaments, sources told ESPN on Wednesday. LIV Golf officials have also had ongoing discussions with other players, including Rickie Fowler and Jason Kokrak.

Johnson and Garcia are among the players who have resigned from the tour, along with 2010 Open champion Louis Oosthuizen, 2011 Masters champion Charl Schwartzel and Kevin Na. The players hoped to avoid punishment from the tour by quitting.
