Former Browns running back Isaiah Crowell found the end zone twice early in the game against his former team and gave the Jets a 14-0.  

After his second score, he was hit with an unsportsmanlike conduct penalty after wiping his butt with the football.

You can celebrate in the NFL, but there is no thrusting and no butt play allowed.  

Crowell probably has no problem taking the penalty here.  He got to show the Browns fans exactly what he thought of them.
