Prosise sustained season-ending injuries in Week 16.Seattle also signed running back Robert Turbin to help fill out the open spots.Both Lynch and Turbin spent part of their NFL careers with the Seahawks, including a few years together. Lynch played for Seattle from 2010 to 2015, while Turbin started out with the team in 2012 and remained there through 2014.Copyright © 2019, ABC Audio. All rights reserved.
