The worst of the bunch is LB Chris Chamberlain who has a turf toe type of injury that will sideline him 6-8 weeks. The Rams will have to make a roster decision in this case. That's a tougher injury than you think. On special teams, they'll probably replace him with Dominique Curry, but Spagnuolo also mentioned Chamberlain's role at weakside LB in the team's nickel package.
CB Kevin Dockery is out for at least the next week with a hamstring injury. CB Justin King is day-to-day with a slightly less serious hamstring injury. CB Jerome Murphy will surely be active for next week's game against the Raiders, but it's important to remember that he's struggled in coverage in the preseason, as rookie CBs often do. It's just a game without Dockery, but we saw what happened in the fourth quarter yesterday when the Rams were forced to use safety James Butler in the nickel defense rather than an extra CB.
Steven Jackson had an MRI today for an inflamed knee. The MRI was negative and he's day-to-day as well. Laurent Robinson has an irritated ankle that will be watched.
