The team downgraded Chark from questionable to out a little more than six hours before kickoff. Chark injured his chest and back making a 45-yard catch in the first quarter of last Sunday’s loss at Tennessee.
Chark has seven receptions for a team-leading 109 yards and a touchdown. He is averaging a team-best 15.6 yards a catch. Without him, Jacksonville will rely on Chris Conley, Keelan Cole and rookie Laviska Shenault against the Dolphins, who are without their No. 1 cornerback in Byron Jones.
The Jaguars also will be without veteran kicker Josh Lambo (hip) and starting center Brandon Linder (knee).
