Camilo Villegas of Colombia has withdrawn from the Olympics, not wanting to miss tournaments as he tries to keep his PGA Tour card.
Villegas also said his decision involved concerns over the Zika virus because he and his wife are trying to start a family.
He is the second golfer in as many days to cite the PGA Tour schedule in pulling out of the Olympics, which has golf on the program for the first time since 1904. Brendon de Jonge of Zimbabwe also is skipping Rio de Janeiro.
Villegas is No. 141 in the FedEx Cup and only the top 125 reach the playoffs and keep a full card for the following season. Villegas would miss two tournaments if he went to Rio.
