Los Angeles - Ninth-ranked Brandt Snedeker has withdrawn from next month's World Challenge golf event hosted by Tiger Woods after suffering a left knee injury earlier this month.
The decision comes two weeks after the American bruised his tibia and strained a ligament in his left knee on November 4 in China when he fell off a Segway vehicle.
The incident took place at a corporate sponsor outing a day after the World Golf Championships HSBC Champions event in Shanghai.
While Snedeker, 32, is ahead of schedule in rehabilitation treatments for the injury, he does not want to risk more damage, particularly with plans for a busy schedule when PGA events resume in early 2014.
Snedeker, who won last year's US PGA playoff title, will defend his Pebble Beach National Pro-Am title in early February and this year he was third or better in four of his first five starts.
Snedeker and South Africa's Ernie Els have withdrawn from the 18-man field for the World Challenge, to be contested at Sherwood Country Club on December 5-8.
