Ravens wide receiver Zay Flowers missed a fifth straight practice Thursday, casting further doubt on his ability to make it back from a knee injury to face the Buffalo Bills in Sunday’s AFC divisional round matchup.

Flowers has not practiced since he hurt his knee in the Ravens’ Jan. 4 regular-season finale. Coach John Harbaugh has said there’s a chance he could play in Buffalo without having practiced all week, but the Ravens are also preparing for what quarterback Lamar Jackson called the “huge challenge” of playing without their leading pass catcher.

They did not have Flowers for their 28-14 wild-card-round win over the Pittsburgh Steelers in which they amassed 464 yards of offense, 299 of those on the ground.

Jackson has expressed supreme confidence in Rashod Bateman, his top wide receiver target with Flowers out of the lineup. “He’s just lighting things up, making my job a lot easier, getting open even more,” the Ravens quarterback said. “And we have a lot of guys on our offense — tight ends, a lot more receivers, running backs — so it’s hard to keep an eye on one guy.”

Offensive coordinator Todd Monken still hopes Flowers will play in Buffalo. If he does not, Monken said the answer is less changing the playbook than identifying other players who can pick up pieces of Flowers’ duties.

“How are we going to move our pieces around to give us the best chance to score?” he said. “That’s what we’re paid to do, irrespective of who takes the field. Hopefully, Zay will be able to go. But if not, we’ve got a lot of really good players. We’re fortunate.”

Returner Deonte Harty, still working to come back from a knee injury, was the only other player to appear on the Ravens’ Thursday injury report.

The Bills, meanwhile, listed sixth offensive lineman Alec Anderson (calf) and reserve running back Ray Henry (concussion) as limited practice participants.
