The Minnesota Vikings may be without quarterback Sam Bradford for Sunday's game against the Pittsburgh Steelers due to a knee injury. 

Per ESPN's Adam Schefter, Bradford will be a game-time decision with the plan being "to work him out pregame."

Per ESPN's Courtney Cronin, the Vikings promoted Kyle Sloter from their practice squad for additional quarterback depth if Bradford can't play. 

Case Keenum is listed as Minnesota's backup quarterback on the official depth chart. 

ESPN's Chris Mortensen reported after Minnesota's season-opening win over the New Orleans Saints that Bradford underwent an MRI on his left knee after experiencing "swelling, pain and discomfort."

Bradford has had his share of injuries dating back to college when he was a star at Oklahoma. He suffered two shoulder injuries in 2009 with the Sooners but still managed to become the No. 1 overall pick in the 2010 NFL draft (St. Louis Rams). 

In three of his first five NFL seasons, Bradford missed at least two games. He hasn't played all 16 contests in a season since 2012, though last year he only missed the Vikings' first game because the Philadelphia Eagles traded him eight days before the regular season started Sept. 11.
