Ravens head coach John Harbaugh said Jackson and "some of the other starters" won't play in Sunday's preseason game at Arizona.
Jackson will watch from the sideline for a second straight week, leaving the Ravens' Aug. 27 matchup with the Commanders as his lone opportunity for an appearance this preseason. It won't be shocking if the Ravens hold him out of that one as well, considering he's a veteran quarterback with a returning offensive coordinator (Greg Roman) and no new pass catchers of note.
