Fournette has been sidelined for the past two weeks due to a hamstring injury. He was listed as questionable after a full return to practice Friday.
The runner seemingly deleted the tweet Saturday morning, which read, "I'm just thankful happy to be back NO WEAPON FORM AGAINST ME SHALL NOT PROSPER see y'all Sunday."
The Jaguars have had mixed results without their offensive focal point. They took down the New England Patriots 31-20 in impressive fashion, only to lose to the Tennessee Titans last week, scoring just six points.
T.J. Yeldon has performed solidly in Fournette's absence in limited work, rushing for 102 yards on 17 carries in two games.
