I'm well aware. You're not allowed to throw the challenge flag though because its automatically reviewed. The rule states its a 15 yard penalty.
Left knee was on the defender's hand. Right knee wasn't down. Ball came out just before the elbow hit. Forearm is not the elbow. AWFUL REVERSE.
this ones all but over now, another game we coulda won blown by shitty playcalling and garbage play by Sanchez
