2003 Oakland Raiders season

The 2003 Oakland Raiders season was the teams's 44th in the National Football League. They were unable to improve upon their previous season's output of 11–5, instead winning only four games. The team had a five game losing streak in the middle of the season, and they lost seven games by a touchdown or less. Their 4–12 record tied them with the Chargers, Giants, and Cardinals as the worst team in football in 2003. For this, Al Davis fired head coach Bill Callahan and replaced him with Norv Turner.

On December 22, the Raiders were on the losing end of a 41–7 score against the Green Bay Packers, led by Brett Favre, playing on Monday Night Football a day after his father died suddenly of a heart attack.
