The Jacksonville Jaguars hope to play with an edge under Gus Bradley and today they got rocking and rolling - literally.

Bradley's two and a half hour practice featured music in the background the entire time.

"We have to do everything we can to get practice at the highest level," said Bradley. "If that means playing music we're going to do that."

The practice featured few breaks and an up tempo style from the coaching staff and the players.

Defensive tackle D'Anthony Smith suffered a calf strain during the session. There were several players who didn't participate because of offseason injuries. New defensive tackle Roy Miller did not participate becaue of tendinitis in the knee and Jeremy Mincey did not practice because of an ear infection.

The Jaguars have two quarterbacks in camp so Bradley was playing qb during some of the linebacker drills.
