What It Means:

Carroll described Walker's injury as unusual, as the exciting rookie is dealing with a strain on the inner part of his foot. The second-round pick will likely undergo further testing this week before the team makes an official decision about his status. The Seahawks are likely to sign another free agent to fill out their backfield with all of Walker, DeeJay Dallas (ankle), and Travis Homer (knee) banged up.

Walker has been electric for the Seahawks this season, picking right up where Rashaad Penny (broken leg) left off. He has averaged 4.9 yards per carry for 649 yards on 138 attempts so far this season, has scored 9 touchdowns in 11 games, and has already caught as many passes as a rookie (19) as he did across his entire collegiate career.
