Lamar Jackson left Sunday's game against Tennessee with a left ankle injury, and the Ravens are treating him as day-to-day while they monitor him, per CBS Sports. The injury came on Baltimore's final offensive snap of the first half. Tyler Huntley opened the third quarter at quarterback with the Ravens leading 24-7.
That's the news. The interesting part is in the scoring column. Baltimore built that 24-7 cushion on Tyler Loop's 64-yard field goal as the half expired, with Jackson on the field. The final was 24-18. Baltimore's offense produced zero points after he left, and Tennessee scored 11 unanswered against a defense that had allowed one touchdown in the first half.
Huntley didn't lose the game. A four-score lead and the defense did enough. But the unit that put up 24 in the first half put up none in the second, and that's the version of the Ravens you'd be buying if Jackson misses time.
Tennessee's line shows how soft the landing was. Cam Ward finished 20-of-31 for 222 yards with one touchdown and one interception, plus 27 rushing yards on four carries, and the Titans still dropped to 0-4, per the team. A Baltimore team that goes scoreless for a half against an 0-4 opponent is not a formula that travels against a competent one.
Day-to-day is a placeholder, not a plan. For a quarterback whose value is tied to what he does with his legs as much as his arm, an ankle is the one injury that muddies the practice report more than the game plan. Baltimore has to decide before the next kickoff whether it's running the full offense or a Huntley offense, because the half-measure is what got them a 6-point win over a winless team.
My call: if Jackson isn't a full participant in practice by the end of the week, start Huntley and build the plan around him. Chasing a limited Jackson is how a manageable injury becomes a three-week problem. The Ravens just proved they can win a game without him. They have not proved they can win the next one that way.
