Coach Jesse Minter noted Tuesday that Jackson and other key starters won't play in Saturday's preseason opener against the Eagles, Jamison Hensley of ESPN.com reports.
There's little to gain by putting Jackson in harms way during the preseason, and there's a pretty solid chance he'll be held out of the team's other two exhibition contests as well. Tyler Huntley, Skylar Thompson (undisclosed) and Joe Fagnano are candidates to handle Baltimore's signal-caller reps this weekend against the Eagles.
