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.

Rory McIlroy was hot and tired when he finished the FedEx St. Jude Championship last year. He was No. 3 in the FedEx Cup. He beat only one player at the TPC Southwind and tied for 68th, finishing 26 shots behind. He dropped all the way to No. 5.
