Brooks Koepka has withdrawn from this week's Travelers Championship, the PGA Tour announced Tuesday night.
The four-time major champion is joining the LIV Golf Invitational Series, sources confirmed to ESPN earlier Tuesday.
Koepka, 32, is one of the highest-profile players to join the breakaway circuit, which is being funded by Saudi Arabia's Public Investment Fund and is fronted by two-time Open winner Greg Norman.
LIV Golf is expected to announce the addition of Koepka in the coming days, sources confirmed. Koepka, who is ranked 19th in the Official World Golf Ranking, is expected to compete in the first LIV Golf event in the United States, at Pumpkin Ridge in Portland, Oregon, starting June 30.
