Jackson was listed as a non-participant in Wednesday's practice due to back and knee injuries.
EDGE Analysis
Earlier Wednesday, head coach John Harbaugh attributed Jackson's absence from practice to rest, but after the team's first Week 9 injury report was released, the quarterback was revealed to be nursing a pair of injuries. Regardless, the Ravens haven't indicated that Jackson is dealing with anything serious, and Harbaugh's comments in particular suggest that the team isn't worried about Jackson missing a home game against the Broncos this Sunday.
