Jackson sustained an ankle injury during Sunday's game against the Titans, Ryan Mink of the Ravens' official site reports.
Analysis:Jackson was seen limping after getting sacked near the end of the first half, and after halftime he was deemed questionable to return. Considering the Ravens have a firm 24-7 lead at the time of the announcement, the team may exercise caution with Jackson and roll with Tyler Huntley unless the Titans happen to close the gap over the final 30 minutes of the contest.
