Report: Erik Walden to face one-game suspension

Indianapolis Colts linebacker Erik Walden will reportedly face a one-game suspension for a headbutt on Tennessee Titans tight end Delanie Walker.

The incident occurred in the second quarter of the Colts' victory over the Titans when Walden struck Walker with his head with his helmet on, while the tight end did not have his protective head gear on.

Walden was not penalised on the field, but following a review of the game by the league, he will now be suspended for at least one game, reports Fox Sports.

The Colts face the Arizona Cardinals in their week 12 clash on Sunday.
