Former U.S. Masters champion Fred Couples has withdrawn from next week's Singapore Open due to illness.
Couples fell sick with a viral illness during Saturday's World Golf Championship at Akron, Ohio, and his doctor has advised him not to travel, Singapore Open organizers said in an statement Thursday.
Couples, who won the Masters in 1992, was to be one of the headliners at the Sept. 7-10 tournament at Singapore's Sentosa Golf Club, which is co-sanctioned by the Asian and European Tours.
Other top participants at the $3-million US Singapore Open include defending champion Adam Scott of Australia, three-time major winner Ernie Els, U.S. Open winner Michael Campbell, England's Lee Westwood and Shingo Katayama of Japan.
