ALAMEDA, Calif. — Lane Kiffin is back at work today as Oakland Raiders coach despite more reports that his firing could be imminent.

Speaking at his weekly news conference, Kiffin says he will assume he is still the head coach until owner Al Davis tells him otherwise. Kiffin says he has not spoken to Davis since before the season opener against Denver on Sept. 8.

Reports about Kiffin's firing first surfaced on the eve of the second game of the season against Kansas City. The team has refused to deny the reports, but Kiffin has remained the coach.
