In the time leading up to the Vikings' first practice of the week on Wednesday afternoon, it was almost as though nothing had changed with Justin Jefferson. The Vikings' top receiver still was moving around their practice facility with his customary optimism, tight end T.J. Hockenson said.
"I've seen him throughout the building. I just talked to him; his mood's high," Hockenson said. "That's a credit to him. He's one of our captains, and a guy that has the same mood every day coming in. That's what we look for in those kinds of people."
It wasn't until the Vikings hit the field Wednesday, for the first practice Jefferson has missed in Kevin O'Connell's two years as head coach, that the 2022 NFL offensive player of the year's absence took its full effect. The Vikings placed Jefferson on injured reserve Wednesday afternoon, with the right hamstring injury he sustained on Sunday, and began the process of preparing for their first game without him since Jan. 3, 2020, when he was a junior at LSU getting ready for the national championship game.
The earliest Jefferson could return is for the Vikings' Nov. 10 game against the Saints, and while O'Connell would not disclose the specific grade of Jefferson's hamstring strain, he said he didn't anticipate the injury would be season-ending, which effectively would rule out a Grade 3 strain.
"I don't want to speculate on exactly when it will be," O'Connell said, "but I know he feels pretty good, considering [the injury] having just been this past Sunday. It's just going to be about all it entails to go through the process, to where he can have some time to start feeling like he can be at full speed again."
In the meantime, the Vikings will try to reconfigure their offense without Jefferson, who has accounted for 26.2% of their targets this season and has 35.7% of the team's targeted air yards, according to NFL Next Gen Stats. First-round pick Jordan Addison, who was limited with an ankle injury on Wednesday, will play a larger role alongside Hockenson and K.J. Osborn, and the Vikings could involve running backs Alexander Mattison and Cam Akers in the passing game to a greater degree.
The Vikings also could see teams approach them differently without Jefferson there to draw double teams. O'Connell said the Vikings could notice the biggest change on third downs and red-zone plays, where teams have been most likely to use true double teams against Jefferson.
"We found different ways at different times to activate him and have some successful plays against those looks," O'Connell said. "But [it's] also what it's done for Jordan on some of those downs, where essentially he finds single coverage and the ability, when the pocket allows, to attack downfield."
