Kansas City Chiefs head coach Andy Reid found himself in an awkward position when he bumped San Diego Chargers quarterback with his rear end during Sunday's game.
Reid appeared to be demonstrating a basketball-style box-out move to a line judge just as Rivers was coming in from behind to argue with the same line judge, leading to the, um, strange turn of events.
Naturally, Rivers was taken a bit off guard, to say the least:
