Coming off their bye week, the Redskins stayed at home for a Week 5 duel with the Detroit Lions. The Lions at that time had never beaten the Redskins in Washington, D.C. Though the first quarter was scoreless, the Redskins began what would be a 14-play 80-yard drive in the second quarter that finished with a 7-yard touchdown pass from Jason Campbell to Chris Cooley. The Redskins' next possession began at their own 17-yard line: in summary, an 83-yard drive in 7 plays, culminating in a touchdown for Mike Sellers in a 1-yard rushing play. The first half ended with the Redskins up, 14-0. With 2:27 left in the third quarter, the Lions scored their first and only points with a 39-yard field goal to bring the score to 14-3. The Redskins' next drive was only 9 yards and resulted in a  punt, but put the Lions on their own 8-yard line. After a rushing play that resulted in a loss of 1 yard, the Redskins sacked Lions' quarterback Jon Kitna in the end zone for a safety, increasing the Redskins' lead to 13 with a score of 16-3 to end the third quarter. After a fourth-quarter fumble by Redskins' running back Clinton Portis, the Lions took possession at their own 10-yard line. The Lions drove 26 yards before punting to James Thrash, who returned the punt for 62 yards and fumbled towards the end zone, where Rock Cartwright recovered the ball on the 3-yard line. After a Redskins' five-yard penalty, Redskins quarterback Jason Campbell threw an 8-yard touchdown pass to Mike Sellers and then converted a two-point attempt with a pass to Chris Cooley bringing the score to 24-3. Detroit's next possession ended with an interception by safety Sean Taylor for a 35-yard return which would later help the Redskins finish a drive with a field goal. With less than 3 minutes in the fourth quarter, the Lions began a drive at their own 43-yard line. After gaining 14 yards, Jon Kitna threw an interception to cornerback Carlos Rogers, who returned it 61&#160;yards for a touchdown for the final score of the game.
