Bryson DeChambeau, Jon Rahm and Cam Smith all committed to LIV Golf after Brooks Koepka returned to PGA Tour

Bryson DeChambeau, Jon Rahm and Cam Smith have committed to LIV Golf after Brooks Koepka announced his departure after four seasons with the Saudi-backed circuit.

The PGA Tour offered a "one-time, defined window" for fellow big names DeChambeau, Rahm and Smith to reapply for membership in what appears to be a power play against LIV.

DeChambeau, Rahm and Smith have a deadline of February 2 to apply for reinstatement if they want to feature this season, with "no promise this path will be available again", according to PGA Tour chief executive Brian Rolapp in an open letter.

"I'm contracted through 2026, so excited about this year," said DeChambeau.

Rahm said: "I'm not planning on going anywhere, so very similar answer to what Bryson gave.

"I wish Brooks the best, and as far as I'm concerned, I'm focused on LIV for this year and hoping my team can repeat as champs."

Australian star Smith, the lowest-profile of the three, said he would be staying with LIV for "years to come."

"I really don't have any thoughts. I haven't had a lot of time to think about it. But I know I'm here to stay. I'm here to support LIV," said the former Open champion. "I'm a captain of a great team and a great group of people. I'm happy where I am. I'm proud of where I am. I think we do many great things, particularly in Australia, and I can't wait for this league to keep growing."
