Highsmith's absence was already known. Aside from the linebacker, this is about as quiet as a mid-season inactives list is going to get. Highsmith is week to week with what seems to be a high-ankle sprain.
After popping up on Thursday's injury report as a DNP, Warren was able to log a limited session on Friday and will be ready to go for Sunday's game against the Ravens. It's hard to know what kind of usage we should expect from Warren, who is coming off a season-high 12 carries for 66 yards in last week's win over the Commanders. Assuming he's operating at close to full strength, Warren is a borderline RB3/RB4 vs. a stout rush defense. The Steelers did declare QB Kyle Allen, RB Jonathan Ward, LB Alex Highsmith, OL Max Scharping, and TE MyCole Pruitt inactive for Week 11.
NFL Network's Ian Rapoport and ESPN's Adam Schefter report that Steelers RB Jaylen Warren (back) is expected to play vs. the Ravens today. He was added to the injury report and did not practice on Thursday but returned to a limited practice on Friday. Pittsburgh elevated RB Jonathan Ward from the practice squad on Saturday, but that's "considered a precaution," Rapoport adds. It sounds like Warren just needs to pass pre-game tests to play today. The back injury adds risk to what was already a tough rushing matchup. But Warren could be busier than usual in the passing game. The Ravens have allowed the sixth most catches to RBs this season.
