JACKSONVILLE – Leonard Fournette won't play again this week.
That was news at Head Coach Doug Marrone's media availability Wednesday morning, but ruling out the starting running back for a fourth time in five games was far from the day's only injury-related news for the beat-up Jaguars.
Left tackle Josh Wells also was ruled out Wednesday with a groin injury, meaning Josh Walker will be the team's third starter at the position in six games when the Jaguars play the Dallas Cowboys at AT&T Stadium in Arlington, Texas, Sunday.
Walker played the second half of a loss to the Kansas City Chiefs Sunday in place of Wells, with Marrone on Wednesday saying of Wells' long-term status:
"I'll know more next week."
Wells started the last three games for Cam Robinson, who started the first two games at left tackle before sustaining a season-ending torn anterior cruciate ligament in a Week 2 victory over New England.
"We've had injuries at the left-tackle position and we've had injuries at running back," Marrone said. "We just need to fill them (the positions) up and keep going."
Marrone on Wednesday also discussed the team's Tuesday recent roster moves, most notably the signing of four-time Pro Bowl selection Jamaal Charles. Charles, 31, played nine seasons with Kansas City before rushing for 296 yards and a touchdown on 69 carries for the Denver Broncos last season.
"He looked good," Marrone said. "He looked in shape. He looked like he was ready to go. We'll see him out on the practice field today."
Marrone said T.J. Yeldon, who has been starting in place of Fournette, will continue to "carry the load for us."
He added of Charles, "He has a track record, but you want to make sure there's production. He looked the part the other day when we worked him out, so we'll see how he does today."
The Jaguars on Tuesday also signed running back Dave Williams from the Denver Broncos' practice squad and tight end David Grinnage from the Jaguars' practice squad. The team on Tuesday placed running back Corey Grant on injured reserve with a foot injury and tight end Austin Seferian-Jenkins on injured reserve with a core muscle injury, while also releasing running back Brandon Wilds.
Seferian-Jenkins could return in mid-December, while Grant is expected to be out for the season.
Marrone also on Wednesday said cornerback D.J. Hayden will miss a fourth consecutive game with a toe injury sustained on the Friday before a Week 3 loss to Tennessee.
*Marrone on Wednesday discussed rookie tackle Will Richardson Jr., a fourth-round selection from North Carolina State who has been inactive in the first five games this season. "We'll find out this week," Marrone said. "He had a little setback in training camp, but we've been trying to speed up that development and we're doing everything we can. He's got to be ready to go."
*The following Jaguars players are also expected to miss practice Wednesday: Hayden (toe), Fournette (hamstring), cornerback Tre Herndon (hamstring), center Brandon Linder (knee), guard Andrew Norwell (foot), Wells (groin) and defensive tackle Malik Jackson (back). Linder has been on the injury report throughout the season with the knee injury, missing practice Wednesdays and starting on Sundays; he also was listed with a back injury last week, but that designation was removed this week. Herndon missed Sunday's loss to Kansas City, while Norwell played through the foot injury against Kansas City. Jackson is new to the report this week. ….
*The following Jaguars players are expected to practice with injuries: right tackle Jermey Parnell (knee), defensive end Yannick Ngakoue (shoulder) and defensive end Calais Campbell (ankle). Parnell and Campbell have been playing through the injuries while Ngakoue sustained the injury Sunday against the Chiefs.
