From the video

He had a very similar injury to what we saw Justin Jefferson have 2 weeks ago and you saw Jefferson produce pretty well yesterday. And these mild kind of medial or high ankle average about 1 to 2 weeks... if he is active, you would see only a mild impact on his rushing production here... with Lamar Jackson, we we've had every game for him this year, he's had at least 20 yards rushing, including a 50-yard game, a 40-yard game.
STACKED’s take
Mild high ankle sprain; borderline week 6 return; only mild rushing impact if active
Suffered a mild high ankle sprain (medial type) with a week 6 return timeline. The source notes Jackson had a very similar injury to what Justin Jefferson had 2 weeks ago, and Jefferson produced pretty well upon return. Mild high ankle sprains average 1–2 weeks recovery; Jackson is on the borderline for week 6 return with a solid chance to play if practice reports trend positively. If active, only a mild impact on rushing production is expected; re-injury risk is not super high given the initial injury was not severe. The source notes Jackson has logged at least 20 rushing yards in every game this year, including a 50-yard game and a 40-yard game, establishing a strong rushing baseline for fantasy consideration.
