Record prize money will be up for grabs on the PGA Tour next season amid the growing threat of the breakaway LIV Golf series.

Dustin Johnson, Brooks Koepka and Phil Mickelson are among the big names who have defected from the PGA Tour to sign hugely lucrative deals with the Saudi-backed LIV Golf.

The PGA Tour on Monday revealed its 2022-23 schedule, which will see prize money for the 43 tournaments they run at $428.6million.

Bonus pools will total $145m, including $75m for the FedExCup. There will be eight invitational events spread throughout the schedule.

The FedEx St. Jude Championship, BMW Championship and TOUR Championship will be the three FedExCup Playoffs events.

Just 70 players will earn a spot in the first Playoffs event in a change to the qualification criteria.

PGA Tour commissioner Jay Monahan said: "We've heard from our fans and the overwhelming sentiment was that they wanted more consequences for both the FedExCup Regular Season and the Playoffs, and to further strengthen events that traditionally feature top players competing head-to-head.

"We feel strongly we've accomplished all of these objectives and more, creating a cadence of compelling drama for every tournament throughout the season.

"Each week has its own identity and purpose, and we're set up for an exciting 2022-23 campaign as we transition into a calendar season in 2024 that will include a number of new and innovative competitive aspects in the fall."
