Marques Colston throws pass across the field for worst play ever

With how quickly Marques Colston turned towards the middle of the field and loaded up to throw the ball across the field, my guess is this was a designed play.  He was right on the sideline and could have easily stepped out and instead he chucked the ball across the field, forwards, and ended the game.  I hope for his sake it was a designed play, because as stupid of a designed play it was, it would have been even dumber for him to do this on his own.
