Missing from Wednesday's announcement, though, were the names of who would be playing, which would affect their PGA Tour membership.

LIV Golf Investments, funded primarily by the Saudi Arabia sovereign wealth fund and headed by CEO Norman, said it is providing more than $US400 million ($A552 million) in "seed money" to launch the LIV Golf Invitational series, which blends 54-hole stroke play with a team concept.

Seven events would have a $US25 million ($A35 million) purse.

The PGA Tour just concluded its richest tournament, with a $US20 million ($A28 million) purse at The Players Championship, won by Australian Cameron Smith.

The series is to start June 9-11 at Centurion Golf Club in St Albans, England, a week before the U.S. Open at Brookline, and will conclude with a team championship at the end of October after events in USA, Thailand and Saudi Arabia.

It features four events in the U.S. One is at Trump National in Bedminster, New Jersey, which originally was to host the PGA Championship this year until the PGA of America voted to move it after the riot at the U.S. Capitol last year.

"We will help in any way possible and will provide golfers with opportunities to achieve their full potential." - Greg Norman.

"Our events are truly additive to the world of golf," Norman said in a news release on Wednesday.

"We have done our best to create a schedule that allows players to play elsewhere, while still participating in our events.

"I believe players will increasingly make progress in achieving their right to play where they want.

"We will help in any way possible and will provide golfers with opportunities to achieve their full potential."

Players who join the PGA Tour are required to play a minimum of 15 tournaments.

According to the regulations, Tour members are not allowed to play another tournament when eligible for a PGA Tour event held the same week without a conflicting event release from the commissioner.

However, regulations say conflicting event releases will not be approved for tournaments held in North America.

Three of the LIV Golf Invitational tournaments would be opposite PGA Tour events – the John Deere Classic (July 1-3), Rocket Mortgage Classic (July 29-31) and an event in September as the Tour starts its new season.

PGA Tour spokesman Joel Schuchmann said the Tour's position hasn't changed from Commissioner Jay Monahan's comment last week that the Tour was "moving on" from talk of a Saudi league the last five months.

The top-10 players in the world have said they are staying put on the PGA Tour.

Along with not stating who has signed up, there was no mention of a television component.
