Per Tom Schad of USA Today, Hendricks punched a police horse and officer at the stadium following his ejection.
Per Philadelphia County Municipal Court records, Hendricks was formally charged with aggravated assault, illegally taunting a police animal, simple assault and defiant trespassing.
Police spokesman Troy Brown wrote in a statement provided to Schad that Hendricks was "punching the horse in the face, neck and shoulder area," and the officer on the horse was being struck in the legs before another officer placed Hendricks in custody.
Hendricks was ejected from Lincoln Financial Field for being intoxicated and not having a ticket to the game. The 22-year-old had his bail set at $5,000 and is due to appear in court on Jan. 30.
