The Vikings put right tackle Brian O'Neill and center Austin Schlottmann on injured reserve Tuesday, two days after both players were knocked out in the first quarter against the Packers.
O'Neill had already been ruled out of Sunday's game against the Bears by coach Kevin O'Connell because of "pretty significant" calf injury. But going on injured reserve means he must sit out four games, effectively ending his season unless the Vikings reach the Super Bowl. O'Neill has been a fixture in the starting offensive line since his rookie season in 2018.
Schlottmann, who was starting at center in place of the injured Garrett Bradbury (back), was lost for the season after sustaining a fractured fibula in his left ankle.
