The Lions will have to play the rest of Sunday’s game against the Vikings without two key defenders.
Edge rusher DJ Wonnum and defensive back Brian Branch have both been ruled out for the rest of the contest with concussions.
The two players collided in the second quarter when they were trying to tackle receiver Justin Jefferson.
It was a direct helmet-to-helmet hit for both players.
The Lions are down 7-6 to the Vikings early in the third quarter.
