I take a punt return back 50 yards and a flag comes in late. The penalty is clipping on #58 P.J. Dawson. I get curious and go check the replay. What I found was not what had happened on the play. Dawson never commits a penalty on the play. Instead, he is the recipient of being hit in the back by a lineman on the opposing team. This cost me not only a great return, but great field position as well. I don't know if this happens on the regular, but I will be watching clipping penalties very closely from now on.

EDIT: This happened again in the very next game on a beautiful kick return TD
