(Renton, WA) -- The Seahawks injury issues aren't getting any better as they head into their final two games. Head coach Pete Carroll says they won't know until tomorrow if running back Chris Carson is ready to begin practicing. Cornerback DeShawn Shead is still on the PUP list and the team won't know if he can be activated until the end of the week. Linebackers K.J. Wright and D.J. Alexander are in the concussion protocol. Defensive tackle Nazir Jones is also a question mark entering Week 16.
