The Baltimore Ravens will be without their top wide receiver when they begin the NFL playoffs against the rival Pittsburgh Steelers, as head coach John Harbaugh officially ruled out Zay Flowers with a knee injury Thursday.

Coach John Harbaugh said earlier this week that the BC product's injury, suffered in the regular-season finale, was not expected to be season-ending.

The Ravens will face the Pittsburgh Steelers on Saturday and the team has announced that Zay Flowers will be out with a knee sprain.
