UPDATE April 6, 3:10 p.m.:
A day after Dustin Johnson took a serious fall down the stairs, the world's No. 1 ranked golfer has withdrawn from the Masters championship, according to the Associated Press.
It appeared that Johnson intended on playing with his back injury. He arrived to the warmup session, but walked slowly toward the first hole.
ORIGINAL STORY: Masters favorite and the world's top-ranked golfer, Dustin Johnson, may not be able to play in the tournament that begins this week after he took a serious fall down the stairs and injured his lower back, the Associated Press reported.
His manager David Winkle confirmed that fall, which occurred at the home he is renting in Augusta.
"He landed very hard on his lower back and is now resting, although quite uncomfortably," Winkle said in an email. "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."

This isn't the first time that Johnson had hurt himself just days before the golf tournament. In 2012, Johnson withdrew two days before the start date after saying he had tweaked his back from pulling a jet ski out of the water.
