The PGA Tour is not backing down from a lawsuit filed by eleven of its former members now playing in the rival LIV Golf league, asking a federal judge on Monday to deny an appeal that would allow three of those players to participate in the FedEx Cup playoffs beginning this week.

The Tour filed a motion to block a temporary restraining order filed by Talor Gooch, Hudson Swafford and Matt Jones that would allow them to compete in the St. Jude Championship in Memphis, Tennessee, beginning on Thursday, arguing that they were aware of the consequences of playing in the Saudi-backed circuit.

"Despite knowing full well that they would breach TOUR Regulations and be suspended for doing so, Plaintiffs have joined competing golf league LIV Golf, which has paid them tens and hundreds of millions of dollars in guaranteed money supplied by Saudi Arabia’s sovereign wealth fund," the tour said in its opposing motion.
