Injuries: Andrew Luck (shoulder) won't practice this week

The centerpiece of the Jacksonville Jaguars' offense returned to the practice field.

Running back Leonard Fournette is back after missing the Jags' Week 7 victory over the Indianapolis Colts with an ankle injury, according to John Oehser of the team's official website.

The rookie's return after the bye week is a great sign for a Jacksonville team that sits tied atop the AFC South at 4-3 ahead of their Week 9 tilt versus the Cincinnati Bengals.

Fournette has been the motor behind the Jags' offense, grinding out 596 rushing yards on 130 attempts, and is tied for the NFL lead among running backs with six rushing touchdowns.

Jacksonville beat the Colts sans Fournette on the back of Blake Bortles' best game of the season, but the Jags need the 2017 first-round pick to power them down the stretch.

The Jags also got receiver Dede Westbrook (core) and center Brandon Linder (illness) back at practice. Left tackle Cam Robinson (ankle) was working on the side, per Oehser.
