Begay declined to comment and kept his head down when asked if Woods was playing in his event, then stopped 20 yards later and said with a smile, I need to win some skins.
Woods agent at IMG confirmed he would be playing Aug. 24 in the Notah Begay III Foundation Challenge. The worlds No. 1 player will join Stanford teammate Begay, former Masters champion Mike Weir and Camilo Villegas.
A year ago, the event raised $180,000 for Begays foundation, which supports youth sports and wellness programs for Native Americans in New Mexico and other states.
Begay, a Navajo, is the only Native American on the PGA Tour. He has four PGA Tour victories, none since 2000, and earned his card for this year by returning to Q-School.
He and Woods have remained closed, however, and Begay received an exemption to the AT&T National, where he opened with rounds of 70-72 at Congressional.
Woods had planned to play in Begays event a year ago until he was forced to miss the second half of the season with knee surgery.
Turning Stone Resort in upstate New York has held a Fall Series event on the PGA Tour the last two years, and its $6 million purse is larger than some regular-season events.
Woods is not expected to play in the PGA Tour event, as it follows the conclusion of the FedEx Cup. Begays charity event is the Monday of The Barclays in New Jersey, the start of the PGA Tour Playoffs for the FedEx Cup. Woods has never played The Barclays since it became part of the playoffs.
Mark Steinberg, his agent at IMG, said Woods has not decided on his schedule for the playoffs.
