Adrian Meronk, the 30-year-old Polish player, who had said he was shocked to be left off the Ryder Cup team, is a four-time winner on the European Tour.
Meronk was set to make his debut this week as a PGA Tour member, having finished in the top 10 in Europe last year, but withdrew from the Farmers Insurance Open at Torrey Pines.
Meronk was runner-up to Rory McIlroy at the Dubai Desert Classic on Sunday after finishing one shot behind with a birdie on the last.
