ALLEN PARK -- After spending the offseason plowing cash and draft picks into their running game, the Lions still aren't done.
Detroit is signing Donnel Pumprey to the practice squad, according to NFL Network. That corrects an early report from NFL Network saying Pumprey was being signed to the 53-man roster.
Pumphrey comes to Detroit after fizzling out in just over a year in Philadelphia. He was taken in the fourth round after leading the nation in rushing in 2016, but struggled to crack a rotation that featured LeGarrette Blount, Darren Sproles and Corey Clement.
