"I just slid off, made a break on the play, and luckily came up with it," Wilhelm said of his interception. "It was a good play."
Wilhelm also added two passes defensed and five tackles.
Drayton Florence picked up his fourth interception, a play that sealed the win. He returned the interception nine yards but amassed at least thirty yards running around the field with the ball.
"In that situation, the smart thing to do is take a knee," he said. "Coach got on me about it and it is behind me now."
Four different Chargers had interceptions on Sunday, the second time they have accomplished the feat this season. Terrence Kiel added his second pick of the season and Adrian Dingle was the recipient of his first career interception.
"Ryan Krause, this is the first day he has been active and he has made a good case for being active (again)," head coach Marty Schottenheimer said.
Malcom Floyd had three catches for 49 yards, including a 13-yard touchdown reception, the first of his career.
"We found out about some guys today, Ryan Krause and Malcom Floyd, that if you have to you can lean on them down the road and you know they can make plays," rookie quarterback Philip Rivers said. "The Chiefs were playing to win."
Andrew Pinnock added 26 yards on 11 carries and he also had a fumble that offensive guard Mike Goff recovered.
Goff thought he scored on the play saying, "I just kept rolling. I thought I might have scored!"
