With their first playoff game four days away, the Seahawks are hoping to boost their special teams as Seattle signed veteran returner Devin Hester yesterday. The Baltimore Ravens waived the 34 year old Hester last month after he struggled through injuries. He holds the NFL record with 20 return touchdowns: a record 14 on punts, five on kickoffs and one return of a missed field goal. Hester spent eight years with the Bears and two with Atlanta. The Seahawks host the Lions in the Wildcard Playoffs Saturday.
