Day pulls out at Doral

Australia's Jason Day withdrew from the WGC-Cadillac Championship at Doral with a thumb injury shortly before the start of play.

The world No 4 pulled out shortly before the start of the opening round on the heavily-revamped Blue Monster course at Doral.

Day admitted he has been troubled by the problem since last month's WGC-Accenture Match Play Championship, where he defied the pain to edge out Victor Dubuisson in an enthralling final.

The Australian is taking no chances just a month ahead of the Masters and now plans to take two weeks off following medical advice, although scans have revealed no significant damage.

"My left thumb was bothering me at the Match Play Championship and the pain continued here this week," said Day, who was one of the pre-tournament favourites in Miami following his win in Arizona.

"I had an MRI in Miami with Dr Lee Kaplan. Fortunately, the MRI was negative, but the doctor prescribed rest if I was unable to play. My plan is to rest for a couple of weeks."

Day, who was scheduled to tee off alongside star pairing Phil Mickelson and Rory McIlroy, last withdrew from a tournament hurt at the 2012 Masters due to a wrist injury.

Meanwhile, his compatriot Brett Rumford fell victim to the vast changes made to the par-five 10th hole as he opened the tournament with a disastrous 11.

Rumford pulled three shots into the water from the tee before eventually tapping in for the first double-figure score of the tournament
