Tiger Woods had just punched out of the woods along the 14th fairway when a highly overzealous Georgia Bureau of Investigation security guard, determined to keep the surging patrons at bay, slipped and almost snapped Woods' ankle.
Pre-tournament favourite Rory McIlroy has plenty of work to do after he shot 71 to sit seven off the pace at even par, while world number one Justin Rose and the respective Masters champions of 2016 and 2017, Danny Willett and Sergio Garcia, all missed the cut at four over.
As rain fell at Augusta National on the closing stages of day two, Woods played his second shot at the 14th from the pine straw to the left of the fairway.
All of the five leaders are major champions and three have been No. 1 in the world.
But the 2013 Masters victor missed a short par putt on the par-3 16th - the bogey dropping him back into a tie for the lead at seven under alongside Day.
"Now I'm just going to rest".
"I put myself in a good place for the weekend", Scott said.
"That's what I'm gonna do today, hit bombs and attack the pin here at the Masters" Mickelson said.
Canada's Corey Conners hits his approach to the fifth green in Friday's second round of the Masters.
"Look, tomorrow is a very important day because there's no doubt someone in the top 15, or a few of them, are going to play very well", Scott said.
He just couldn't take the next step - one more birdie on a back nine filled with so many chances - to join the largest 36-hole logjam in Masters history.
"Accidents happen, we move on", Woods said of the incident, confirming he suffered no major damage from the guard's boot.
Can either make some serious headway in the second round? No one who has covered the Masters for years can remember anything quite like this happening. And now he goes into the weekend one shot behind, the closest he has been to a lead going into the weekend at a major since the 2013 British Open at Muirfield.
Day said he had his chiropractor working tirelessly on his back on Thursday night and Friday morning to get him ready to play through the injury.
He knocked in the eagle putt to move to eight-under par.
