As part of the changes instituted by head coach MIke McCarthy this season, his Green Bay Packers will hold a practice the day before a game for the first time on Friday.

It will be a busy day for the Packers as they hold a practice early in the day before traveling to Nashville in advance of Saturday's game against the Tennessee Titans.

"We're traveling later, going down to Tennessee, than we normally have, but that's because we're doing more with (Friday's) practice than we would with a 53-man roster," said McCarthy.

Friday's practice is the first one not open to the public this training camp, and one of three total which fans will not be able to attend.

The change in schedule, practicing the day before a game, has to do with sports science and the players' neurological clock, according to McCarthy, in a belief players will be operating at peak performance on game days after instituting such a change.

Also on Friday, former Packers quarterback Brett Favre—just days after being announced he will be inducted into the team's Hall of Fame and have his number retired in 2015—will join 620 AM WTMJ in the morning hours, according to Steve Wexler, executive vice president of Journal Broadcast Group:
