The Ravens have only one defensive lineman, Nnamdi Madubuike, who is not on the injury report, but the situation evolved Friday.

The Ravens placed Michael Pierce (calf) on injured reserve earlier this week and Brent Urban (concussion) was ruled out after not practicing all week.

Travis Jones (ankle) and Broderick Washington (knee) returned to practice Friday, but Jones is still questionable to play. Washington doesn’t carry a designation, which means he’s expected to match up.

If the Ravens need additional help on the defensive line, they have several defensive linemen they could bring up from the practice squad: nose tackle Josh Tupou, defensive end Chris Wormley, rookie defensive end CJ Ravenell and defensive end Adedayo Odeleye.

“Obviously we have some guys that are getting hit. We’ll see if they make it to Sunday’s game,” defensive coordinator Zach Orr said Thursday.

“Obviously these lads are very important players for us but I’m delighted with the lads we have at the back – they’ve been working well in training. Here in Baltimore, the interior of the D-Line is something we take for granted. seriously, and we always have a contingency plan for that, and I don’t think it’s really going to change the way we call (play).”

The strength of the Broncos’ offense has been their rushing game, which ranks 14th in the league at 121.4 yards per game. Javonte Williams is their leader and rookie quarterback Box Nix can make some plays with his legs as well.
