A source briefed on the player's condition tells NFL.com and NFL Network's Ian Rapoport that Jones-Drew's foot injury won't require surgery. The source said Jones-Drew does not have a season-ending Lisfranc fracture, but he'll miss a "significant" number of games.
Jones-Drew has already been ruled out for Week 8 for what is being termed a foot sprain. It remains unclear just how many games the Jaguars will be forced to go without their best player.
With Jones-Drew down, Rashad Jennings becomes Jacksonville's starting running back. Jennings scored a rushing touchdown on Sunday, but managed just 44 yards on 21 carries.
