The Minnesota Vikings activated quarterback Sam Bradford off injured reserve Saturday morning and moved him to the 53-man roster.
Bradford, who was placed on IR on Nov. 8 with a left knee injury, returned to practice last week and completed his fifth practice Friday.
Between Case Keenum, Teddy Bridgewater, Bradford and Kyle Sloter, the Vikings now have four quarterbacks on the 53-man roster. Tight end Kyle Carter was waived Saturday to make room for Bradford.
Bradford has played in one full game this season when he torched the New Orleans Saints in Week 1 for 346 passing yards and three touchdowns.
