The opening of this year's football season has brought some changes in how referees will be miked.
Working with ESPN, the SEC has decided to put a wireless microphone on every official instead of just the head referee.
Unlike the head ref's mic, which is designed to be heard by tv viewers and by the live audience through the stadium sound system, the additional mics are intended for communication between officials in order to facilitate discussions and decisions.
The SEC and ESPN are hopeful that this experiment will make games move more quickly, since the officials will no longer need to be physically close to one another in order to communicate.
The system was first tried during LSU's spring intersquad game and coach Les Miles gave it his approval.
