Jason Day has sent a scare through the Australian tilt at the Masters, limping away from the driving range with a foot complaint.

World No.11 Day, a runner-up last year, was practising on Tuesday when he tweaked his left foot, apparently aggravating an injury suffered last week.

There was some concern the highest-ranked of the six Australians could follow American Dustin Johnson (back) as a high profile withdrawal from the year’s first major championship.

But 24-year-old Day remained confident he’d be ready to start Thursday’s first round.

“It’s nothing big and at this stage I still intend to play,” Day said.

“There was some discomfort but it would take a lot for me to miss a Masters.”

Day’s manager Bud Martin confirmed Day had arrived at Augusta National carrying an injury.

“Jason injured his left ankle and foot training last week but he is getting treatments from his trainer today and tomorrow,” Martin said.

“We are optimistic Jason will be fine by Thursday.”

Day and fellow Australians Adam Scott, Geoff Ogilvy, John Senden, Aaron Baddeley and amateur Bryden Macpherson will attempt to end the countries 76-year drought at the event.
