Bryan Kehl, Nick Sundberg done for 2013

ASHBURN, Va. -- The Washington Redskins’ special teams has enough problems. Two more can be added to the list. They lost their top tackler, Bryan Kehl, and long snapper, Nick Sundberg, to season-ending knee injuries.

Both Kehl and Sundberg were hurt in Washington’s 31-16 loss at the Dallas Cowboys on Sunday night.

Kehl tore his left ACL while Sundberg tore the meniscus in his right knee. They’ll weaken an already weak crew under first-year coach Keith Burns. Sundberg is an excellent long snapper and gets the ball back quick. Kehl was one of the leaders on special teams, an area that has kept him in the NFL. The Redskins lack impact players on these units and therefore can’t afford any loss of a good player. The Redskins have not yet signed anyone to take the place of either player.

Corner David Amerson suffered a concussion in Sunday’s loss and will be monitored throughout the week.
