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.

In an effort to reduce his overall workload on the season, Masters champion Rory McIlroy decided not to play in this week's St. Jude Championship at TPC Southwind in Memphis, Tennessee. As such, the first leg of the FedEx Cup Playoffs will run with 69 of the top 70 players in the world -- McIlroy the lone missing piece from the start of the three-week postseason.

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.
