The Tournament Players Club at Summerlin and TPC Canyons will remain in the rotation, and the Bear's Best course will replace Southern Highlands.
The tournament is scheduled for Oct. 7-10.
Golfers will play Bear's Best and the Canyons once each and Summerlin twice, with the final round at Summerlin.
The tournament will retain its pro-am format, and amateurs will play the first three days. The final round will be for professionals only.
Tournament chairman John Sullivan said the event went to a 72-hole format to accommodate PGA Tour players who are competing in the American Express Championship, which is being held the previous week in Kilkenny, Ireland.
Bear's Best is a collection of 18 holes designed by Jack Nicklaus.
