The PGA Tour have suspended the 17 members playing in the first event of the controversial LIV Golf Invitational Series.

The news was confirmed in a memo signed by Tour commissioner Jay Monahan on Thursday.

Phil Mickelson, Dustin Johnson and Sergio Garcia are among those to have been suspended, though the latter two are among those who have notified the Tour that they have resigned their membership.

Louis Oosthuizen, Lee Westwood and Ian Poulter are also among the other notable names featuring at the three-day event that will have 12 teams and 48 players

Graeme McDowell, Kevin Na, Charl Schwartzel, Hudson Swafford, Talor Gooch, Branden Grace, Matt Jones, Andy Ogletree, Peter Uihlein and Turk Pettit are the others included in the memo.

Monahan confirmed the decision to prohibit those players from playing on all features of the PGA Tour, including the Korn Ferry Tour, PGA Tour Champions, PGA Tour Canada and PGA Tour Latinoamerica.

The breakaway golfers will also be removed from the FedEx Cup rankings following this week's RBC Canadian Open and will not be eligible for the FedEx Cup or Presidents Cup.

"These players have made their choice for their own financial-based reasons. But they can't demand the same PGA Tour membership benefits, considerations, opportunities and platforms as you," the memo read. 

"That expectation disrespects you, our fans and our partners."

Garcia, Westwood and Johnson were among 10 players to resign from the Tour to pursue their LIV Golf interests, but Monahan added they will not be granted sponsor exemptions to play in tournaments as non-members.

Bryson DeChambeau and Patrick Reed have been widely reported to have signed up to the lucrative series, though neither are playing this weekend.

Monahan said any players who do take part in future LIV events will face the same consequences.

The decision comes amid the widespread backlash against the controversial, Saudi Arabia-backed breakaway, with many accusing the event of sportswashing.

Greg Norman, a two-time Open champion and LIV Golf's CEO, suggested Saudi Arabia is "making a cultural change".

Mickelson found himself at the centre of the controversy last year when admitting to being aware of Saudi Arabia's human-rights record but signed up to LIV Golf anyway because "this is a once-in-a-lifetime opportunity to reshape how the PGA Tour operates".

On the eve of the first tournament, Mickelson received a grilling from the media, and he told reporters: "I don't condone human rights violations, I don't know how I can be any more clear.

"I understand your question but again I love this game of golf, I've seen the good it's done and I see the opportunity for LIV Golf to do a lot of good for the game over the world and I'm excited to be a part of this opportunity."

World No17 Johnson is the highest-ranked player on the current LIV Golf list and acknowledged he did not initially know the repercussions of his decision, but said he had chosen "what's best for me and my family".
