JACKSONVILLE, Fla. (AP) Cody Kessler's return to Jacksonville lasted seven plays and ended with a slow walk to the visitors' locker room.

Philadelphia's third-string quarterback was knocked out of the team's 24-10 preseason victory against the Jaguars on the opening drive Thursday night. Defensive end Datone Jones came unblocked off the edge and walloped Kessler in the back.

Kessler was escorted to the sideline, evaluated for a head injury in the locker room and then placed in the concussion protocol. The team already was without backup Nate Sudfeld, who broke his left wrist in the team's preseason opener against Tennessee. Starter Carson Wentz rested for the second straight game. He watched from the sideline in uniform, but without pads and a helmet.
