Jackson didn't participate in Tuesday's practice due to a knee injury.
In Week 9, Jackson sat out practices Wednesday and Thursday with knee and back injuries, but he put in a full practice Friday before lighting up the Broncos in Sunday's 41-10 win. Though he was removed early amid the blowout and finished with his fewest carries of the season (three) while throwing just 19 passes, Jackson is apparently still bothered by the knee issue coming off the light workload. Tuesday represents the Ravens' only full practice of the week prior to Thursday's game against the Bengals, but head coach John Harbaugh suggested that Jackson is in no danger of missing the Week 10 contest, per Jamison Hensley of ESPN.com.
