Coach Jack Del Rio planned to give fullback Greg Jones a bigger role in the offense this year. Unfortunately, it will not happen. The Jaguars announced on Monday that Jones will miss the season after undergoing surgery to repair a torn ACL in his left knee. The third-year player suffered the injury in Saturday's preseason game against Tampa Bay. Del Rio initially believed the injury to be a sprained MCL, but an MRI revealed that Jones had a torn ACL.
