Phil Mickelson drops out of LIV Golf lawsuit against PGA Tour

• The Justice Department opened an investigation into the PGA Tour over antitrust violations in July.

What they're saying: "Plaintiff, Phil Mickelson voluntarily dismisses without prejudice his claims against Defendant," one of the filings reads.

• Talor Gooch, Ian Poulter and Hudson Swafford also asked to be removed as plaintiffs in the lawsuit.

The big picture: Four other golfers who were included in the original suit —Abraham Ancer, Carlos Ortiz, Pat Perez and Jason Kokrak — are no longer part of it, according to ESPN.

• Bryson DeChambeau, Matt Jones and Peter Uihlein remain plaintiffs, as well as LIV Golf, which joined a few weeks after the lawsuit was filed.
