Injury roundup: C.J. Prosise a game-time decision

The Seattle Seahawks might be without their promising young running back, but they're not panicking.

Seahawks coach Pete Carroll told reporters Thursday that running back C.J. Prosise is a game-time decision against the Falcons. Prosise, who hasn't played since Week 11 after suffering a shoulder injury, was a full participant in practice on Thursday.

Thomas Rawls could again dominate the workload, but their depth behind him is extremely thin.

Fifth-round rookie Alex Collins would be Seattle's backup in case Prosise can't play.

Here are some other injuries we are tracking:

1. Cowboys cornerback Morris Claiborne (groin) was a full participant in practice after being limited on Wednesday. Offensive tackle Tyron Smith (knee) and defensive end DeMarcus Lawrence (back) were limited.

2. Packers wideout Jordy Nelson (ribs) and running back James Starks (concussion) didn't practice. Guard T.J. Lang (foot) and cornerback Quinten Rollins (concussion) were limited.

3. Chiefs linebacker Justin Houston (knee) was a full participant in practice.
