Michael Huff intercepted Matt Schaub's pass in the end zone on the final play to secure the win. Coach Hue Jackson dropped to his knees on the sideline, covered his face with his hands and cried as his team celebrated the bittersweet victory.
Sebastian Janikowski kicked four field goals, three from at least 50 yards. He was one of those unorthodox moves Oakland was known for under Davis, becoming only the third kicker drafted in the first round when the Raiders took him in 2000.
"He was looking over us," Janikowski said. "I was feeling good and hitting everything in warmups."
Stadiums around the league observed a moment of silence before the early games to honor Davis, who died at his Oakland home on Saturday at age 82. The Raiders (3-2) wore black decals on the backs of their helmets with "AL" written in silver letters.
