Let's just let ESPN's Adam Schefter explain why the Ravens will practice Wednesday without their starting QB: "Lamar Jackson is not practicing today in a COVID-related case the league still is trying to process, per Jamison Hensley and me. Jackson, who tested positive on Thanksgiving, had another test that NFL officials flagged. NFL now going through science, and Ravens awaiting answers." We'll see where this situation goes. It's impossible to tell at the moment whether this is something that will only cost Jackson a day or 2 -- or an issue we should be concerned about. Jackson, of course, had the positive test last November that cost him a game. But we hadn't heard of any related issues since. For now, we're not adjusting Jackson's fantasy outlook.
