Offensive coordinator Greg Roman relayed Thursday that Jackson is dealing with a back flare-up and should be fine, Jeff Zrebiec of The Athletic reports.
That said, Roman noted that the team is in "wait-and-see" mode in terms of the QB practicing Thursday. With that in mind, we'll circle back on Jackson's status once the Ravens re-take the field, but for now at least, his availability for Sunday's game against the Broncos does not appear to be in any danger.
