Rams coach Steve Spagnuolo rested Steven Jackson all week, told me: "We knew the only shot he had was to rest it all the way through. It’ll be a tough call."
It sounds like the Rams aren't ruling him out for tonight. A lot of times players who don't practice won't play, but Jackson is clearly a vet and knows the offense enough to step right into a game. Brian Westbrook owners can probably relate.
Hopefully owners have both backs, but if you're a Caddy Williams owner you may be stuck with a surprise Jackson start you weren't counting on. Caddy should still get his share of the workload even if Jackson starts.
