The Buffalo Bills and the Baltimore Ravens are facing injury concerns ahead of their divisional round playoff matchup on January 19. The Bills' rookie running back Ray Davis is still in the concussion protocol after leaving last week's game with an injury, while the Ravens' key wide receiver Zay Flowers is dealing with a knee issue that has kept him sidelined during practice.

Davis has been listed as a limited participant in practice but carries a questionable status for the game. He has had a productive rookie season with 631 scrimmage yards and six touchdowns. In contrast, Flowers, a Pro Bowl selection this year, has been officially designated as doubtful to play.
