Johnson resigns from PGA Tour | USGA: LIV golfers can play US Open

Dustin Johnson has confirmed he has resigned from the PGA Tour in order to compete in the Saudi-funded LIV Golf Invitational Series.

Speaking alongside fellow major-winners Louis Oosthuizen and Graeme McDowell at a LIV press conference at the Centurion Club on Tuesday, Johnson said he resigned his membership from the PGA Tour, which makes him ineligible for next year's Ryder Cup.

The former world No 1 expressed his excitement for the controversial new format, adding he believes it will be a 'true test.'

"Obviously at this time it's hard to speak on what the consequences will be, but for right now, I've resigned my membership from the PGA Tour," Johnson said. "I'm going to play here for now, and that's the plan.

"What the consequences are going to be, I can't comment on how the tour is going to handle it.

Later on Tuesday, the USGA confirmed that golfers competing in this week's LIV series opener will be allowed to play in next week's US Open, providing they had already qualified.

A statement said: "Regarding players who may choose to play in London this week, we simply asked ourselves this question - should a player who had earned his way into the 2022 U.S. Open, via our published field criteria, be pulled out of the field as a result of his decision to play in another event? And we ultimately decided that they should not.
