The Minnesota Vikings are turning to their backup plan against the Pittsburgh Steelers.

Quarterback Sam Bradford is inactive Sunday with a knee injury, leaving Case Keenum to fill in as starter.

Bradford participated in warmups and was listed as questionable for the game after being limited in practice throughout the week. He twice tore the anterior cruciate ligament in his left knee when he was a member of the St. Louis Rams.

Keenum signed with the Vikings this offseason to be Bradford's backup. He served as the Los Angeles Rams' starter last season before giving way to Jared Goff midway through the year.
