Fournette practiced without limitation all week and was not designated on the Jaguars' final injury report, but head coach Doug Marrone was not ready to say he will play.
"We'll see on Sunday, but he has done everything that we have asked him to do," Marrone said on the Jaguars' official website on Friday. "No setbacks. No nothing. Right now, he's completely healthy -- today, at this time."
Barring a setback, Fournette is expected to be in the starting lineup on Sunday because the Jaguars (3-5) need him after losing all four games during his absence.
The 6-foot, 228-pound Fournette has only 71 yards on 20 carries this season after rushing for 1,040 yards and nine touchdowns on 268 carries last season as a rookie, while adding 36 receptions for 302 yards and a score.
The Jaguars made Fournette the fourth-overall pick of the 2017 NFL Draft out of LSU.
Jacksonville ruled out cornerback A.J. Bouye (calf) and rookie cornerback Quenton Meeks (knee) for Sunday's game, while listing linebacker Telvin Smith (shoulder), tight end James O'Shaughnessy (hip), tight end David Grinnage (knee) and defensive end/linebacker Lerentee McCray (hamstring) as questionable.
