The PGA Tour has come down hard on players who are teeing it up in the LIV Golf Invitational Series

The PGA Tour has banned all players who are teeing it up in the LIV Golf Invitational Series and those who play in future events.

In a strongly worded letter from commissioner Jay Monahan, the Tour says that LIV Golf players are "suspended or otherwise no longer eligible to participate" in PGA Tour events.

They will 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 letter reads.

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

The latter specifically mentions a number of players, with asterisks referring to those who have already resigned their membership:

The likes of Bryson DeChambeau, Patrick Reed and Rickie Fowler are all reported to be signing with LIV Golf, meaning they would also lose their PGA Tour memberships.
