"At roughly 3:00 pm today, Dustin took a serious fall on a staircase in his Augusta rental home," the statement read.

He has been advised to remain immobile and begin a regimen of anti-inflammatory medication and icing, with the hope of being able to play tomorrow."

Johnson, the reigning US Open champion, is the favourite to win the green jacket and record is best Masters finish last year with T-4.
