The San Francisco 49ers host the Arizona Cardinals in the NFC West Bud Light Good Sport DD Challenge, which is a competition between three NFL teams: the Arizona Cardinals, San Francisco 49ers and Seattle Seahawks. The winner of the Bud Light Good Sport Designated Driver Challenge will be the NFL team with the most total points at the end of the 2017 regular season. Points are earned when fans pledge to be Good Sports – designated drivers – at NFL games and when fans show their support for their favorite NFL team’s responsibility efforts on Facebook.
