Bell appears to be finished in the race. He was downgraded to kick return duty and he tweaked an ankle on Sunday.
Combine Bell's ineffectiveness and lack of durability, with Anderson's inability to move the chains and fumblitis, and Dayne's steamrolling of a pretty good san diego run defense in the 4th quarter, and I think its very reasonable to assume that Dayne could emerge as the clear #1 against the chiefs on sunday.
