Golf star Rory McIlroy has received a warning that he may not be able to skip the FedEx Cup's opening playoff event indefinitely. The reigning Masters champ is currently the sole golfer out of the 70-man lineup who has chosen to sit out this weekend's whopping $20 million showdown at TPC Southwind.

That's because Rory McIlroy, who ranks second in the FedEx Cup standings behind only Scottie Scheffler, is skipping the first playoff event to prepare for the BMW Championship and Tour Championship. The PGA Tour isn't thrilled with his contentious decision.

After a challenging stretch, Rory McIlroy seemed to find his rhythm again during the Scottish Open and The Open Championship, looking far more settled on the course. He reached the summit in April by winning The Masters and completing the Career Grand Slam.
