PGA Tour to increase cash prizes in revamp | Koepka to join LIV

The PGA Tour is laying out plans to increase purses at several marquee events and revamp its schedule with Brooks Koepka expected to join the Saudi-backed LIV Golf Invitational series.

Sky Sports News understands that the four-time major winner - who has removed all references to the PGA Tour from his social media profiles - will tee it up in the second event in Portland next week.

The 32-year-old is set to become the latest big name to join the controversial series, following Dustin Johnson, Bryson DeChambeau and Phil Mickelson, and has withdrawn from Thursday's PGA Tour event, the Travelers Championship in Connecticut.

LIV also announced on Tuesday that world number 20 Abraham Ancer has also joined LIV and will play in next week's event, but world No 4 Collin Morikawa has denied talk that he's set to follow.

The two-time major winner, and defending Open champion, tweeted on Tuesday: "To state for the record, once again, you all are absolutely wrong. I've said it since February at Riviera that I'm here to stay on the @PGATOUR and nothing has changed."

The PGA Tour is set to announce plans to compete with the burgeoning LIV Golf Invitational Series.

PGA Tour commissioner Jay Monahan reportedly unveiled plans to increase the purses at limited-field events in the regular season to at least $20m and establish a new, lucrative fall schedule for the top 50 finishers in the FedEx Cup standings.

Those new tournaments would rotate sites around the world and - like LIV's tournaments - have no cut.

Monahan is scheduled to speak with the media at TPC River Highlands on Wednesday, with the tournament beginning Thursday.

Newly-crowned US Open champion Matt Fitzpatrick has also reiterated his commitment to the PGA Tour and DP World
