It looks like Kansas City Chiefs quarterback Matt Cassel was right earlier this week when, as everyone was doubting that he would play Sunday because of a rib injury, he said he was "ready to roll." Cassel practiced in full Friday, finishing a week of nothing but full practices from him. He is listed as probable on the injury report and is expected to play against the Buffalo Bills.
Wide receiver Steve Breaston was added to the injury report Friday after going through limited practice. He has a hamstring injury and is also listed as probable.

Fantasy Analysis:

Defenses are generally unpredictable from year to year, but the Bills were hideous against the run last season. I expect the Chiefs to attack them with a lot of Jamaal Charles and Thomas Jones, limiting Cassel's chances to produce. He's an OK start, but he's better used as a QB2. Breaston shouldn't be in your lineup.
