Benny Cunningham

Cunningham was originally released by the Jaguars on Aug. 11. Tuesday's workout is important for the 29-year-old because it means he's clear of the hamstring injury that plagued him early in training camp. Detroit already has four healthy running backs on its active roster, but Cunningham could find a spot on the practice squad if he impresses the team Tuesday.

Cunningham was thought to be absent from Thursday's preseason opener due to his veteran status, but he appears to have been dealing with a hamstring injury. The 29-year-old seemed to have a decent chance of cracking the Jaguars' 53-man roster as a third-down back, but he'll have to look to latch on elsewhere once healthy.

Cunningham is likely receiving the day-off due to his veteran status, with nothing to prove unlike young players. Alfred Blue, Ryquell Armstead and Devante Mays stand to handle the running back duties with a slew of players out for the Jaguars.

Cunningham primarily has served as a special teams player and third-down back throughout his career, handling 191 carries and 147 targets. He was barely used last season in Chicago, but he still has an area of expertise that differentiates him from the other running backs on Jacksonville's roster. Alfred Blue has 673 career carries and just 69 receptions, while rookie fifth-round pick Ryquell Armstead (hamstring) caught 29 passes for 175 yards (6.0 average) in four seasons at Temple. It appears the Jaguars will use either Cunningham or starter Leonard Fournette on passing downs.
