VIDEO: Cowboys' Jason Witten not happy on the sidelines

Dallas Cowboys tight end Jason Witten isn't normally one to get fired up and yell at his teammates, but frustration for the Cowboys is at an all-time high Thursday. 

Witten ripped into the sideline with the Cowboys trailing the Philadelphia Eagles 23-10 late in the third quarter. 

You know things aren't going well when Witten appears more animated than Dez Bryant.
