England's Ross Fisher withdrew from the World Golf Championships-Bridgestone Invitational on Monday.
Fisher, ranked 64th in the world, is staying at home to be with his wife and their ill three-month-old son Harry, according to a sportinglife.com report.
Fisher's manager Conor Ridge told the website that "Harry should be fine -- it looks like it's just precautionary."
Fisher has played in three previous Bridgestone events, with his best finish coming in 2009 when he finished 43rd. His best World Golf Championships result also came in 2009 when he was a semifinalist at the Accenture Match Play Championship.
