Erik Walden Headbutts Delanie Walker After Taking Off Helmet in Titans-Colts Game (GIF)

The Indianapolis Colts won a physical AFC South game over the Tennessee Titans on Thursday night to improve to 7-3 on the season.

While football fans can appreciate an intense, physical effort in a rivalry game, Colts linebacker Erik Walden took his aggression way too far in the second quarter by taking off Titans tight end Delanie Walker‘s helmet, then headbutting him.

Somehow, Walden escaped an ejection and was only given a 15-yard penalty for unnecessary roughness. No one will be surprised if the six-year veteran receives a fine, or even a suspension, for his actions on Thursday.
