Four of the 125 players who qualified for the FedEx Cup playoffs will skip the first leg of the four-event series this week in New Jersey.
No. 9 Rory McIlroy, No. 31 Sergio Garcia, No. 99 Francesco Molinari and No. 111 Retief Goosen will all skip The Barclays at Plainfield Country Club in Edison, N.J.
McIlroy made the announcement ahead of the PGA Championship, suggesting a continued recovery from a July 4 ankle injury sustained while playing soccer with friends. With two wins in May, McIlroy is assured a spot in the Tour Championship, so a week off will cause little disruption to his ranking.
Garcia didn't supply a reason to the PGA Tour for his playoff truancy.
Both Molinari and Goosen have family issues to attend to, with the Italian choosing to be at home with his wife, who is pregnant with the couple's second child. Goosen didn't disclose specifics of his family situation to the PGA Tour.
Molinari and Goosen will bow out of the playoffs after The Barclays, with the top 100 in the standings moving on to next week's Deutsche Bank Championship.
On Monday afternoon, Louis Oosthuizen withdrew from the event, citing a back injury.
There are no alternates for playoff events, meaning that just 120 players will tee it up at The Barclays.
