The Green Bay Packers' ailing passing game will have to step up big time against the Dallas Cowboys on Sunday.
The Packers are extremely thin at running back, with Eddie Lacy as the only rusher on the active roster. Wide receiver Randall Cobb will have to serve as the backup running back, according to NFL Media.

Lacy is dealing with a sprained ankle that limited his practice time during the week. Practice squad member Don Jackson took several first-team reps with backup James Starks in Buffalo due to a death in his family.
Cobb's career average is seven yards per carry.
