We'll be checking in periodically with officiating updates. Here are some referee stats through the first four games. The chart below breaks down each referee by penalties per game, total replay challenges, total replay reversals, total replay reversal rate, coaches' challenge reversal rate, booth challenge reversal rate and challenges per game. We must note that each referee works with a crew, so it's not like Mike Carey is calling a league-high 17.8 penalties per game on his own. Likewise, we can't necessarily blame Gerry Austin for having a league-high three replay reversals. But he is the head guy, so we list the stats associated with his crew.
NOTE: Officiating information culled from official NFL gamebooks. In some cases the gamebooks do not include all declined penalties. For this reason, official stats will differ slightly.
Note: Penalties are all penalties called, not just those accepted.
