Cardinals inside linebacker Deone Bucannon left the game because of a right leg injury as he helped assist on a tackle of Jaguars running back Leonard Fournette.
He walked to the locker room under his own power.
Looks like it could be a right knee situation. Check back for updates.
Cardinals score first, 3-0
Blaine Gabbert completed 4 of 5 passes, including a 26-yarder to tight end Ricky Seals-Jones on third down, and the Cardinals got a 34-yard field goal from Phil Dawson to take a 3-0 lead over the Jaguars on their first possession of the game.
