Vikings coach Kevin O'Connell said in his Monday afternoon press conference he didn't know yet on Monday how long Justin Jefferson could be out because of the hamstring injury that sidelined him during Sunday's 27-20 loss to the Chiefs. Then, early Tuesday morning, a source confirmed the team plans to place him on injured reserve, meaning he'll miss the next four games.
Jefferson's absence will mean significant short-term changes for the Vikings' passing game. The receiver has 53 of the Vikings' 199 targets this year, and had an even larger percentage of them last year, when he received 184 of the team's 641 targets.
