Lamar Jackson threw three touchdown passes and ran for a score to carry the Ravens (9-5) to their third straight win following a three-game skid. Robinson was limited to 35 yards rushing before leaving in the fourth quarter with an ankle injury. The highlight of the fourth quarter was a 22-yard first-down run by Baltimore offensive lineman Tyre Phillips with a Jackson fumble.
