Jones (illness) did not participate in Wednesday's walkthrough practice, Demetrius Harvey of The Florida Times-Union reports.
Jones maintained his usual snap share (47) in the Jaguars' Week 18 win over the Titans, but the 24-year-old will miss the team's first practice heading into wild-card weekend. He'll likely need to practice in some capacity Thursday or Friday to have a chance at playing against the Bills on Sunday.
