With a number of injuries at running back, the Jacksonville Jaguars have signed Jamaal Charles.

Leonard Fournette is out indefinitely with a hamstring injury and No. 3 running back Corey Grant was placed on injured reserve with a Lisfranc injury in his left foot.

T.J. Yeldon, the starter in Fournette's absence, has a nagging ankle injury.

The Jaguars also promoted first-year back Brandon Wilds from the practice squad.

"I've been trying to do all my condition work, just trying to stay in shape just in case I got anybody to call," Charles said. "The reason why I wanted to come here, really, was because I wanted a potential shot at a Super Bowl. That's why I still kept my options open. I really want to win a championship."
