Vikings running back Bishop Sankey suffered a torn right ACL in the third quarter of the Vikings' win over the Bills on Thursday night, according to an NFL source and will miss the 2017 season.

Sankey, a second-round pick by the Titans in 2014, was the first running back drafted that year, with the 54th overall pick. He was signed to the Vikings' practice squad last November, and carried four times for 14 yards in the Vikings' preseason opener before injuring his leg on a 14-yard run in the third quarter. He was on crutches with a brace on his right knee in the Vikings' locker room after the game, and an MRI on Friday showed he tore his ACL. The only other Vikings running backs to log carries on Thursday night were Terrell Newby (who ran 12 times for 26 yards), second-round pick Dalvin Cook and fullback C.J. Ham. The team played on Thursday night without veterans Latavius Murray and Jerick McKinnon, who sat out because of injuries.
