MINNEAPOLIS -- The Lions' linebacker depth took another hit Sunday when Paul Worrilow was injured in Detroit's 14-7 victory over the Vikings with a left knee injury.
Worrilow injured the knee on Detroit's first defensive play of the game, a Dalvin Cook run. He was helped over to the sideline, examined on the training table and carted back to the locker room. He did not return to the game.
Lions coach Jim Caldwell said they are "going to have to wait and see what the final prognosis is" on Worrilow, but he did not give an idea of what the initial prognosis was, either.
The fifth-year pro was playing because starting middle linebacker Jarrad Davis was inactive for the second straight week as he recovers from both a concussion and a neck injury. It's not clear which injury kept Davis out of the game.
In other Lions injury news, both running back Ameer Abdullah and Caldwell said Abdullah could have returned to the game after his foot injury in the fourth quarter.
