The San Francisco 49ers will likely be without cornerback Tramaine Brock in Week 4 against the Philadelphia Eagles, but he could be back in the near future. Brock has been out since suffering turf toe in Week 1. He is still not participating in practice, but according to Matt Maiocco, Brock is no longer wearing an orthopedic boot on his foot.
Brock has been wearing the boot to relieve stress on his sprained toe, and naturally that prevents him from practicing. He is still not practicing, but removing the boot means we can probably expect him back sooner rather than later. This Sunday will be three weeks since the injury. Maiocco mentioned the injury typically requires at least a month of recovery. That can extend to 6 or so weeks, but it varies by injury.
For now, the 49ers will stick with Perrish Cox and Chris Culliver as their starting cornerbacks, and Jimmie Ward in the nickel. Chris Cook and Dontae Johnson offer backup services. Johnson got the edge in Week 1, but it appears Cook has moved past him for now on the depth chart. Last week against Arizona, Cook had 15 defensive snaps and 9 special teams snaps, while Johnson just had 9 special teams snaps. There has been no real word on how that depth chart shakes out on a week-to-week basis.
