Tim Clark of South Africa withdrew the day before the start of the Humana Challenge in La Quinta because of tendinitis in his left elbow, which also forced him to pull out of the Sony Open in Hawaii midway through the second round last week.
The 38-year-old Clark, who finished second in the Humana Challenge in 2005 and 2010 when it was known as the Bob Hope Classic, is scheduled to have an MRI on the elbow sometime this week.
Clark, who is 18th in the FedEx Cup standings after tying for second in the McGladrey Classic in October by closing with a 62, underwent surgery to repair a torn tendon in his right elbow in August of 2011, when the injury limited him to only 11 starts.
Daniel Chopra of Sweden, who regained his PGA Tour card by finishing 21st on the Web.com Tour money list in 2013, replaced Clark in the field.
Steve Jones, the 1989 Bob Hope Classic champion who also captured the 1996 U.S. Open, withdrew for undisclosed reasons and was replaced in the Humana field by Bronson La’Cassie.
