The 2020 Master's champion, who jumped ship to the controversy-marred LIV Golf last week, resigned from the PGA Tour during a Tuesday press conference.
Johnson said Tuesday that he joined the new league because it was "what's best for me and my family."
Johnson will no longer be able to play in the U.S. team in the future due to his resignation.
This is a story that is evolving.
The Royal Bank of Canada stopped sponsoring golfers Johnson and McDowell after they decided to leave the PGA tour.
