(Renton, WA) -- The Seahawks are shuffling their roster as they head into Week 16. The team waived LB Kache Palacio, who was promoted from the practice squad last week. No corresponding move with Seattle's 53-man roster was listed. The Hawks could be keeping a roster spot open for cornerback DeShawn Shead. Shead would need to be activated off PUP within the next week in order to be eligible to play this season. The Seahawks also signed defensive back Alex Carter and defensive end Noble Nwachukwu to the practice squad.
