A day after being hit with an unsportsmanlike conduct penalty that cost the Redskins 15 yards in the closing moments of Sunday’s loss to the Bengals, offensive coordinator Kyle Shanahan released a statement about what led to his being flagged.

Here is Shanahan’s statement:

“When I overheard the official tell the head coach that the game was over after the false start penalty, I tried to explain that the game was not over. This is what resulted in the unsportsmanlike conduct penalty. I tried to get an explanation of how I could get that penalty when half of the other team was on the field as well.

I was frustrated, and in the process of trying to get some answers from officials, I conducted myself in the wrong way.

I ask our players to hold themselves to a high standard and be accountable and I know that I’m accountable for my actions as well.

I know that I need to handle those situations better in the future. My emotions got the best of me and I know it’s my responsibility. This will never happen again.”
