JACKSONVILLE, — Jacksonville Jaguars running back Maurice Jones-Drew will miss Sunday’s game at Green Bay, maybe more, because of a foot injury.

Quarterback Blaine Gabbert has a chance to play despite an injury to his non-throwing shoulder. Jones-Drew injured his left foot on the first play of Sunday’s 26-23 loss at Oakland. Gabbert injured his left shoulder on a sack in the second quarter.

Coach Mike Mularkey says he doesn’t have results of tests performed on Jones-Drew’s foot, but adds that the injury is serious enough that it could keep the running back sidelined for an extended period. Mularkey says team doctors haven’t ruled out the possibility of it being a Lisfranc injury.
