Ravens coach John Harbaugh declined to say whether Jackson would start Sunday.

Now, after his most extensive work since injuring his hamstring 26 days ago, there's a chance that Jackson could be back at a time when the Ravens need him the most. Baltimore has lost four straight games to fall to 1-5, which ties the worst start in franchise's 30-year history.

Jackson was not made available to reporters on Friday.

If Jackson is unable to play, Harbaugh said Huntley would start against the Bears. Huntley would get the nod over
