We’ve already seen Adrian Colbert placed on injured reserve with a high ankle sprain. D.J. Reed took his spot at free safety. Reed got a couple snaps at nickel back as well when K’Waun Williams briefly left the game. Jimmie Ward could eventually get an opportunity to compete at free safety once healthy, but for Week 8, look for Reed to get the full workload.
The running back position saw Matt Breida aggravate his ankle sprain. He played five offensive snaps before being shut down. Raheem Mostert played 22 snaps and Alfred Morris played 20. Morris was looking like he would spend the game complementing Breida. Mostert was the complement against the Packers in Week 6, but Kyle Shanahan has said there will be a rotation based on the matchup.
Cornerback Richard Sherman was inactive with a calf strain, and it’s safe to say his status will be touch and go for the foreseeable future. When asked if Sherman’s injury was something they’ll have to manage week in and week out, Shanahan said:
“Yes. Yeah, it’s been wearing on him as the year has gone. Some weeks have been better than others. Last week was a bad week. We’ll see how he feels this Wednesday when he gets back in ready to go.”
Ahkello Witherspoon and Greg Mabin started at the two cornerback positions, with K’Waun Williams serving as the nickel back. Tarvarius Moore got 12 snaps and Tyvis Powell played four snaps. The 49ers return to practice on Wednesday, at which point they will re-assess Sherman and Ward. My guess is both sit out Wednesday’s practice, but we’ll see what comes of it.
The defensive line was one other interesting position. DeForest Buckner had the bulk of the work with 40 snaps, but this week Solomon Thomas was next on the depth chart. He finished the game playing 38 snaps. He had 15 at defensive tackle and 23 on the edge. That’s a step up for a guy who’s best pass rush work has generally come from the interior.
