This tweet came from the Star's Phillip B. Wilson:
"#Colts RB Joseph Addai said today he is a long shot to play Sun. at Cincinnati. Hamstring will keep him out, IMO."
If Addai is on your fantasy roster, then you'll likely need to replace him for this weekend's games.
The waiver wire has a few candidates who can fill in this week:
Delone Carter, Colts
Possibly the best option to replace Addai resides in the Colts' own backfield. Carter figures to get the majority of Addai's carries in Cincinnati, and he scored a touchdown filling in last week.
Carter will sacrifice a few carries to Donald Brown, but I'd expect Carter to get the lion's share on Sunday.
Earnest Graham, Buccaneers
If LeGarrette Blount has to sit on Sunday, the Bucs backfield will be Graham's. That's looking like a probable scenario at this point. Last week, Graham carried the ball five times for 30 yards in Blount's absence.
Stevan Ridley, Patriots
Most have already jumped on the Ridley bandwagon, but join them now if he's still available.
Ridley should be getting more touches this week with a banged-up BenJarvus Green-Ellis, and if that's the case, Ridley could have a big performance against Dallas. The Pats have been running the ball more, and with effectiveness.
