Foster, the NFL.'s leading rusher in 2010, has a sore knee and Reed has a sore hip. Kubiak is "optimistic" that both players will be ready, but he'll work out both of them before Sunday's game.
Kubiak says Foster "practiced fine" on Thursday. He says Reed came out of an individual drill and felt a "twinge" in his hip.
Ben Tate would start for Foster and first-round draft pick Whitney Mercilus would start for Reed, if either regular starter can't go on Sunday.
