Chris Long taunts Josh morgan after his boneheaded mistake

On Sunday, Redskins wide receiver Josh Morgan made a big mistake by getting called for a 15 yard unsportsmanlike penalty after throwing a football at Rams cornerback Cortland Finnigan for pushing him down.  It was a big mistake because it was during a potential game winning drive within the final few minutes of the game.  The penalty ended up pushing the Redskins out of field goal range., and they ended up losing by three points.

Below is evidence of Rams defensive end Chris Long taunting Morgan after the play.

I’m not sure if the regular official would have penalized Long for his kind gesture.  I wonder if this is just another blunder by the replacement officials.
