Phil Mickelson may yet have to testify in the ongoing legal battle between LIV Golf and the PGA Tour, despite withdrawing his name from the lawsuit.

Mickelson, Talor Gooch, and Hudson Swafford removed their names from the antitrust lawsuit LIV Golf filed against the PGA Tour in August, but a judge has now ruled they are still subject to discovery in the case.

U.S. District Court Judge Susan van Keulen has ruled that player agents are subject to disclosure, including non-privileged information stored and transmitted electronically.

Judge Van Keulen ruled in favor of continued discovery, saying it "applies regardless of whether the responsible person is a litigant or a third-party entity."

Attorneys for Mickelson, Gooch, and Swafford argued that the PGA Tour's discovery process could reveal information and communications from other agents' clients regarding LIV Golf.

The court agreed that information about other players should not be disclosed, so it ordered that the search be "designed to limit the scope of results to materials.

Interestingly, Van Keulen also ruled that DP World Tour chief executive Keith Pelley and the R&A could be ousted,

The lawsuit, if it eventually goes ahead, is not expected to be heard in court until 2024 as the bitter feud between the PGA Tour and LIV Golf continues and runs.
