The Jacksonville Jaguars had two huge setbacks in Oakland.
They lost star running back Maurice Jones-Drew early and a 14-point lead late.
How they handle both could determine whether the Jaguars (1-5) recover from the one of the worst starts in franchise history.
Jones-Drew injured his left foot on the first play of Sunday's 26-23 loss to the Raiders in overtime. He wasn't able to play through the pain and spent the second half on crutches and wearing a protective boot.
Coach Mike Mularkey said Monday that Jones-Drew will be sidelined at least for Sunday's game at Green Bay, maybe longer.
''I was just disappointed that he didn't get a chance to really show his stuff out there because I felt like that he was going to have a good game for us,'' Mularkey said.
Mularkey said the injury is serious enough that it could keep MJD sidelined for an extended period. Mularkey said team doctors haven't ruled out the possibility of a Lisfranc injury.
