Carson Palmer has thrown more pick-sixes than any other active quarterback in the NFL over the past 10 years, so this news might not come as any surprise to you: Palmer threw a pick-six.
The big play came on the Cardinals' opening drive against Dallas on Sunday.
Palmer was on a roll before the interception, he was 2 of 3 for 23 yards, but then on the eighth play of the game, Palmer's luck ran out and Cowboys defensive back Tyler Patmon did this.
The Cowboys have shot out to a 10-0 first quarter lead in Dallas. You can follow the Cowboys-Cardinals game on our CBSSports.com game tracker here.
