The Jaguars are working to protect the health of running back Maurice Jones-Drew. He had offseason surgery on his right knee and may not play in a game until the regular season. Jones-Drew could get a few carries in Jacksonville's third preseason game, but coach Jack Del Rio wouldn't commit to any timetables. "We have a plan," Del Rio said. "He's fully compliant and understands that we've got to have a plan. We've got to execute that plan, and part of that is getting him to the season as healthy and prepared as possible. He does need to have some contact, but we'd like that contact to be controlled as long as we can. That's why he won't be playing this week."
