Johnson, who injured himself in a freak accident when falling at his rented house in Augusta yesterday afternoon, had spent much of the night working on the injury but despite heading to the driving range this morning in the hope that he could swing the club well enough to compete, it soon became clear he could not.
“We treated it all last night and this morning – I went out and tried to hit balls and I could swing maybe 70 per cent," said Johnson.

"The backswing was fine, I could take it, but it was impact and through impact that was where it would catch to the point where I felt I wasn’t able to compete.
"It (the decision) is unbelievably difficult – this is one of my favourite tournaments of the year and I feel I am playing the best golf of my career right now and for me to pull out, it sucks.
"The worst part about it is that I feel, in two days, I am going to be fine. It is just that right this second, I can’t swing."
