The return of Pittsburgh Steelers wide receiver Antonio Brown from a high-ankle sprain that sidelined him for three games creates a matchup issue for the Ravens.
The Ravens will have to account for his versatile presence Sunday at M&T Bank Stadium.
Brown is the most versatile all-purpose threat on the Steelers' offense.
Brown is regarded as extremely dangerous and made the Pro Bowl squad last year.
He ranks third on the Steelers with 42 catches for 499 yards and one touchdown. He has 28 first downs.
Since the start of last season, Brown ranks sixth in the league with 76.6 percent of his receptions resulting in first downs behind Malcom Floyd, Vincent Jackson, Calvin Johnson, Rob Gronkowski and Roddy White.
Last season, Brown piled up 2,211 all-purpose yards to break Barry Foster's franchise single-season record.
He became the first player in NFL history to have at least 1,000 receiving yards and 1,000 kick return yards with 1,108 receiving yards and 1,062 return yards.
"He's definitely one of the top receivers in the league, I think," Ravens cornerback Cary Williams said. "He's very versatile. He can run any route. He can run inside, he can run outside. He has great body control. He has great hands and ability to run after the catch."
