Redskins LS Nick Sundberg is done for the season with a knee injury. The Redskins have a borderline-unhealthy affection for Sundberg, using their injured reserve/designated return device on the long snapper in 2012 before signing him to a four-year extension in the offseason. This time, his injury is too severe for the Redskins to keep Sundberg on the roster.

Redskins agreed to terms with LS Nick Sundberg on a four-year contract. 26-year-old Sundberg was shockingly given the "designated for return" tag after fracturing the ulna in his arm in last year's season opener. The Redskins could have used that designation on a more valuable offensive or defensive player, but clearly have a high opinion of Sundberg's long-snapping abilities.
