Jalen Ramsey listed as questionable for Sunday's game against Dallas Cowboys

Jacksonville Jaguars cornerback Jalen Ramsey is officially listed as questionable for Sunday's game against the Dallas Cowboys, and head coach Doug Marrone said he is legitimate "50-50" to play.

Ramsey was added to the injury report on Thursday and was limited Thursday and Friday due to knee soreness. He played in Week 3 after being listed as questionable, but that was due to an ankle injury.

The Jaguars will be without cornerbacks D.J. Hayden (toe) and Tre Herndon (hamstring) against Dallas after both sat out practice all week.

Marrone told reporters that Hayden and running back Leonard Fournette -- who was ruled out for Sunday earlier this week with a hamstring injury -- both have a chance to play in Week 7 after running on a side field Friday.

Fournette has yet to finish a game this season, tweaking his hamstring in Week 1 and aggravating it during his return in Week 4. A Florida Football Insiders report earlier this week suggested the Jaguars could hold Fournette out through their Week 9 bye to make sure he avoids re-injury.

The Jaguars will also be without left tackle Josh Wells (groin) and long snapper Carson Tinker (knee), who were both placed on injured reserve.

Wells has been filling in for Cam Robinson since the starter tore his anterior cruciate ligament in Week 2, but the team will now move forward with former Giants first-round pick Ereck Flowers, who was signed Friday. Per an NFL Network report, there is hope Wells can return later this season.

The team signed long snapper Matt Overton to the roster to take Tinker's place. Overton replaced Tinker for nine games last season after Tinker tore his ACL. Overton spent his first five seasons with the Indianapolis Colts.
