Bruce Gradkowski threw a 29-yard tying touchdown pass to Louis Murphy with 33 seconds left and Sebastian Janikowski kicked a 33-yard field goal after Andre Caldwell fumbled the ensuing kickoff, giving the Raiders a 20-17 victory Sunday.
The Bengals (7-3) have lost all 10 games in Oakland, including one playoff game.
Oakland (3-7) rallied from an early 14-point deficit and trailed 17-10 with 2:06 left when it took over at the 20-yard line. Gradkowski, who took the starting job from JaMarcus Russell this week, threw a 19-yard pass to Zach Miller, and a 16-yarder to Chaz Schilens on fourth-and-10.
After a spike to stop the clock, Gradkowski found Murphy near the goal line. Murphy got loose from Morgan Trent and dived across the goal line.
