World number two Jason Day has withdrawn from the WGC-Mexico Championship, which starts on Thursday, due to illness.
In a statement released by the PGA Tour, Day said: "I'm truly disappointed to announce that I won't be able to play in next week's World Golf Championship-Mexico Championship.
"I have a double ear infection and the flu, which precludes me from preparing for and playing in the tournament.
"I have heard great things about the Mexico Championship and the golf course. I want to thank the Salinas family for their support of the event [which is sponsored by Grupo Salinas]. I look forward to teeing it up there next year."
Day, who has been plagued by various injury problems throughout his career, was replaced as world number one by Dustin Johnson last week after the US Open champion won the Genesis Open.
