Ravens wide receiver Rashod Bateman and Pro Bowl center Tyler Linderbaum appeared on the team’s penultimate injury report after missing Friday’s practice at Owings Mills three days before Monday night’s crucial showdown against the host Los Angeles Chargers.

Bateman, who is second on the team in catches (33) and receiving yards (531) this season, is listed with a knee injury, although he was in good spirits and did not appear to be in pain after the snowfall in the locker room session. Linderbaum, meanwhile, missed practice with a back injury and his replacement, rookie Nick Samac (chest), was limited.

On the other hand, running back Justice Hill (concussion protocol) and wide receiver Nelson Agholor (illness) were both full participants after Hill was limited a day earlier and Agholor was ill.

The biggest concern for Baltimore (7-4) heading into its showdown with the Chargers (7-3) remains the status of All-Pro inside linebacker Roquan Smith, who did not practice for the third straight day in the loss due to a hamstring injury Sunday against the Pittsburgh Steelers.

“It’s going to be a challenge if Roquan can’t go,” defensive coordinator Zach Orr said Friday, adding that Smith’s role will be filled by a committee of Trenton Simpson, Malik Harrison and Chris Board when he doesn’t play. “Not one person will replace Roquan. Roquan is an every-down linebacker (and) a top linebacker in this league (and) All-Pro for a reason. Nobody will replace him. We like the people we have in the room – they’re here for a reason and someone (has to) step in.”

There were no changes to the rest of the Ravens’ injury report, with safety Kyle Hamilton (neck) and outside linebacker Odafe Oweh (neck) both being full participants for the second straight year and defensive tackle Travis Jones (ankle), rookie safety Sanoussi Kane (ankle). and cornerback Arthur Maulet (calf) are all no longer practicing.

The Chargers, on the other hand, appear to be getting healthier with some key players back on the field.

The main workouts on Friday were outside linebackers Khalil Mack (groin) and Joey Bosa (hip), rookie wide receiver Ladd McConkey (shoulder), tight end Hayden Hurst (hip) and rookie cornerback Cam Hart (concussion/ankle).
