Jackson is expected to make his first NFL start Sunday against the Bengals with Joe Flacco (hip) listed as doubtful and unlikely to be available, Adam Schefter of ESPN reports.

After failing to practice this week and carrying the doubtful designation into gameday, Flacco looks poised to miss out on his first start since the 2015 season. While that opens the door for Jackson to get his first extended run under center, Jeremy Bergman of NFL.com relays that the rookie is expected to share snaps with veteran Robert Griffin. Jackson had the misfortune of sitting out on Thursday's practice while recovering from a stomach bug, and though he's seemingly healthy now, the missed practice time might have been enough for the Ravens to maintain a role in the game plan for Griffin as well. The uncertain distribution of snaps makes Jackson somewhat of a volatile fantasy option this week, though his running skills undoubtedly make his upside high, particularly against a porous Cincinnati defense.
