Jack Nicklaus, winner of 18 majors, told The Palm Beach Post the linking of the previously warring organisations is "good for the game of golf".

His comments came days after saying he no longer considered LIV players "part of the game".

But Tuesday was a new day for the sport and its direction of travel.

"The last three years have been difficult for the game and the players," Nicklaus told the Post.

"I spoke with PGA Tour commissioner Jay Monahan this morning. He seemed pleased with the arrangement that will once again bring together the best players in the world.

"I agree that this is good for the game of golf.

"Jay indicated that this all will happen in 2024, so very soon the proof will be in the pudding.

"Whatever is best for the game of golf enjoys my full support."

Nicklaus said he was offered $US100 million ($A150m) by Saudi Arabia's Public Investment Fund to be the CEO of the upstart circuit, a post that eventually went to Australian Greg Norman.

Nicklaus said at the time LIV "wasn't for me".

Just last week Nicklaus was asked about LIV players who weren't able to compete in his Memorial Tournament in Ohio because they had jumped ship to the rebel series.

"I don't even consider those guys part of the game anymore," he said then.

"I don't mean that in a nasty way. This is a PGA Tour event, and we have the best field we can possibly have for a PGA Tour event from those who are eligible to be here.

"The other guys made a choice of what they did and where they've gone and we don't even talk about it."
