James Starks is now the Green Bay Packers' top running back, replacing the slumping Eddie Lacy.
Coach Mike McCarthy said before practice on Wednesday that Starks is the team's "No. 1 back right now" entering this weekend's game against Detroit.
McCarthy says the team will stick with a one-two punch at running back. Starks typically received chunks of playing time when he came off the bench.
Lacy was an 1,100-yard rusher in each of his first two seasons in the league. But he has tailed off this year with just 308 yards rushing on 83 carries in eight games.
Lacy sprained an ankle in Week 2 and left Sunday's loss at Carolina with a groin injury.
