Masters and US Open winner Jon Rahm joined the LIV tour in 2023

Saudi Arabia will withdraw its multi-billion dollar backing of LIV Golf at the end of the season, plunging the future of the series into further doubt.

According to sources, the breakaway tour is set to announce on Thursday a "new strategic plan" in a bid to find replacement financial investors.

The breakaway tour will also confirm new independent board members as it tries to move forward with fresh leadership.

It comes amid reports that the Saudi Public Investment Fund (PIF) could confirm that its governor Yasir Al-Rumayyan is stepping down from LIV's board.
