World No. 10 Sepp Straka of Austria withdrew from the BMW Championship on Monday due to a private family matter, leaving the field for the FedEx Playoffs event shy of the expected 50 qualified players.
"For personal reasons, Sepp is unable to play this week. He intends to compete at the Tour Championship, but requests privacy at this time as he attends to a family matter at home," said Butler Melnyk, Straka's manager, in a statement released to media on Monday.
Straka has two wins this season and is fifth in the playoff standings and sixth in the European Ryder Cup standings. He tied for 17th in the playoff-opening event in Memphis last week.
He has six top-10 finishes this season and won The American Express and the Truist Championship.
Last week, Northern Ireland's Rory McIlroy withdrew from the FedEx St. Jude Championship.
As PGA Tour playoff rules stipulate, only qualified golfers will participate this week, meaning Straka will not be replaced in the field.
