Sankey (knee) cleared waivers and reverted to the Vikings' injured reserve, Chris Tomasson of the St. Paul Pioneer Press reports.
Sankey tore his right ACL in the Vikings' preseason opener and was waived two days later. He should have plenty of time to recover in time for the 2018 campaign, but since the 25-year-old was on the roster bubble in 2017 prior to the serious injury, his NFL career seemingly hangs in the balance. Second-year running back Bronson Hill was signed to take Sankey's place on the training-camp roster.
