American Brooks Koepka is set to quit the PGA Tour and join the Saudi Arabian-backed LIV Golf series.

The four-time major champion, 32, is expected to play in the second 54-hole, 48-man tournament that runs from 30 June to 2 July in Portland, Oregon.

The Ryder Cup player will join compatriots Phil Mickelson, Dustin Johnson and Bryson DeChambeau in the new $250m (£200m) eight-event series.

The PGA Tour suspended 17 members who played in the inaugural LIV event.

On Tuesday it was announced that 31-year-old Mexican Abraham Ancer, the world number 20, has signed up to play on the LIV Golf series.

Koepka has withdrawn from Thursday's PGA Tour event, the Travelers Championship in Connecticut.

Speaking at the US Open, where he finished 55th on 12 over, Koepka complained that questions over the LIV event were throwing a "black cloud" over the major.

The former world number one won the US Open in 2017 and 2018 and is also a two-time US PGA Championship champion, claiming the Wanamaker Trophy in 2018 and 2019.

Koepka rose to the summit of the game at that period, but he has been hampered by injuries in recent years and is ranked 19th in the world.
