The news couldn't be worse for the Minnesota Vikings.
NFL Network Insider Ian Rapoport and NFL Network's Tom Pelissero reported that Dalvin Cook's knee injury is believed to be a nearly complete tear of his ACL based on an initial diagnosis for the rookie running back, per sources informed of the situation.
Cook is "hopeful" a subsequent MRI will reveal otherwise, but chalk Sunday up as a devastating setback for the rookie and his team.
Murray and McKinnon will likely be hot pickups this week on the waiver wire. Murray finished with seven rushes for 21 yards and did have two catches while McKinnon wasn't much of a factor running twice for no yards and he didn't catch a ball. McKinnon probably makes the most sense for PPR leagues while Murray may be a better standard league fit.
