- Judges and broadcasters work from separate tables.

- Fighter Anthony Pettis described the feeling inside the ring. “It’s hard to assess without the crowd. When I land stuff, I hear the crowd and know it was a good one. This time, there was no crowd. I saw his head pop, but there was nothing behind it, so it’s hard to tell.”
