Brown injured his ankle last week against the Pittsburgh Steelers and didn’t practice all week.
A first-round pick by the Ravens, Brown leads all rookies this season in receptions (21) and receiving yards (326). He is tied with Terry McLaurin for the most touchdown catches by a rookie with three.
Willie Snead could become Lamar Jackson’s top target in Brown’s absence. Snead has had at least 50 yards receiving in his last two games.
Tight end Mark Andrews will play Sunday. Andrews previously dealt with a foot injury. Now he's dealing with a shoulder injury that sidelined him for a handful of plays last game. Andrews could be in line for a big outing against the Bengals, who have allowed an NFL-worst 15.2 yards per catch to tight ends.
