Labor Day was Day 1 of the healthiest week the Vikings will enjoy until their season ends in early January or, if they shock the universe, the second week in February when Super Bowl LIX is held in New Orleans.

“I’m 100 percent, good to go for Sunday,” said cornerback Shaq Griffin, who has battled a right hamstring pull since Day 2 of camp.

All 53 players on the active roster were on the field for stretching Monday as the Vikings kicked off a Week 1 schedule that will conclude with Sunday’s season debut at the New York Giants. That included receiver Jordan Addison, who moved well but didn’t participate in the individual drills during the brief period that reporters are allowed to watch practice.

Addison injured his left ankle Aug. 14 in a joint practice with the Browns. He’ll be the name to watch when the week’s first injury report is released Wednesday.

Linebacker Blake Cashman was injured during the same practice that felled Addison. Cashman broke a finger in the facemask of a Browns running back during pass rushing drills early in the practice, finished the workout and was told he’d need surgery.

“It was more frustrating and annoying than anything, having to have a little procedure done on a little finger,” Cashman said. “I missed like six or seven practices, but I’m feeling good. Just glad it wasn’t anything to worry about.”

Week 1 in the NFL gets more unpredictable by the year as preseason work for frontline players ranges from nothing to minimal at best. Justin Jefferson, Harrison Smith, Aaron Jones, Jonathan Greenard, Andrew Van Ginkel and Griffin are among the key stars who didn’t take a preseason snap. Sam Darnold, Christian Darrisaw, Brian O’Neill, Garrett Bradbury and Addison took 12 snaps in the first game. Josh Metellus, Cam Bynum, Byron Murphy Jr. and Cashman took 14, and Harrison Phillips 11.

How in the world do these guys go from three weeks of game days in which they meander the sideline like guys at the beach to the crazy intensity of 60-plus snaps come Week 1?
