Two first-half touchdowns from rookie Jordan Addison set the Minnesota Vikings on the way to a 22-17 win over the San Francisco 49ers.

Christian McCaffrey, an injury doubt ahead of the game, matched him with two scores of his own but it was not enough as the 49ers slipped to a second successive defeat.
