UPDATE: Dustin Johnson's trainer, Joey Diovisalvi, told Tim Rosaforte of Golf Digest on Thursday morning that Johnson is "up and moving around and definitely going in the right direction. He was very much in an under-control point going to bed last night. He was walking around, a lot more mobility, took a couple of practice swings slowly without a club."
Is it still unclear, though, if Johnson will tee it up Thursday afternoon.
"He told us, 'I'm going to do everything I can to go out and play tomorrow,'" Diovisalvi said. "That basically is his attitude. He was playing with [his son] Tatum. Life sometimes happens. He's not angry or upset. I'd say more discouraged."
The Masters favorite is now questionable to start the tournament.
Dustin Johnson injured himself falling down stairs Wednesday afternoon, but according to his agent, hopes to still play in the event.
"At roughly 3:00 pm today, Dustin took a serious fall on a staircase in his Augusta rental home," Johnson's agent David Winkle said. "He landed very hard on his lower back and is now resting, although quite uncomfortably. 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. I will refrain from commenting further until I know more about Dustin's condition."
Johnson, who has won three straight events, is widely considered the favorite to win this week. He will play in the final group Thursday, beginning at 2:03 p.m. ET. For more tee times, check out the entire list here.
