Things got chippy on Thursday Night Football when Indianapolis Colts linebacker Erik Walden ripped off Tennessee Titans tight end Delanie Walker's helmet. It didn't stop there, as Walden, who was still wearing his helmet, headbutted Walker in the face.
Check out the series of events below:
Walden was flagged 15 yards on the play for unnecessary roughness, but he wasn't ejected. It was the third consecutive play in which the Colts had committed a personal foul.
The penalties helped the Titans get a field goal on the drive to take a 17-3 lead late in the second quarter.
