The Indianapolis Colts already expect Dwight Freeney not to play for several weeks because of a left foot injury, but now there's reason to believe the Pro Bowl defensive end's season might be over. Though more tests have to be completed for the team to make a final determination, a source said Tuesday that Freeney might have suffered a Lisfranc injury in Sunday's loss to the San Diego Chargers. If additional tests verify the initial diagnosis of the midfoot injury, the source said Freeney will need season-ending surgery. Players who have suffered Lisfranc injuries, even those not needing surgical repair, have needed months to rehabilitate.
