The Ravens will be without a key wide receiver Saturday against the Steelers, as Nelson Agholor has been downgraded from questionable to out due to a concussion.

Agholor didn’t practice all week after coming down hard from a leaping catch last Sunday against the New York Giants. Head Coach John Harbaugh said Thursday that Agholor had enough time to potentially clear concussion protocol and play, but he wasn’t ready.

Agholor has 14 catches for 231 yards and two touchdowns this season. He caught three passes over the past five games.

The Ravens would be even more short-handed at wide receiver if Rashod Bateman, who is questionable with a foot injury, can’t play. Diontae Johnson has been waived.

Zay Flowers will lead Baltimore’s wide receiver group, but they could turn more to Tylan Wallace, who has caught all 10 of his targets for 191 yards, and rookie Devontez Walker, who made his first catch and touchdown last week against the Giants.

Tight end Isaiah Likely could end up seeing more snaps and/or targets as well.

“Just staying ready,” Likely said Thursday. “[I’m] harping on the little things when you go into the game, so when your number is called, those big plays happen, so they got to keep honest to everybody.”

The Steelers will be without leading wide receiver George Pickens (hamstring), so both teams may have to pivot in a critical AFC North matchup with the division title on the line.
