Latest I've heard:
Maroney: Likely to play as he made a go of it last week but just didn't feel quite alright. I'd expect him to be ready this week.
Morris: Speculation that he could be out 2-4 weeks. Nothing certain yet, but that is likely correct.
Faulk: Going to get some carries/catches no matter what, but unlikely to make much of a fantasy dent this week if Maroney plays.
