Josh McCown, who started the first three games this season for the Raiders, remains unavailable due to a broken big toe in his left foot. McCown did not practice Monday and wore a protective walking boot on his left foot. Kiffin has already ruled McCown out against the Chargers.
"I prepare the same no matter what," Culpepper said of his status as Oakland's starter. "It's no different to me. No matter what my role is or what time it is, I'll be ready to play."
With Culpepper as quarterback, the Raiders scored 35 points in the win over Miami, the most by an Oakland team since 2005.
