McKinnon (back) won't participate in Saturday's team scrimmage, Andrew Krammer of the Minneapolis Star Tribune reports.
Although McKinnon returned to practice Friday, the Vikings will continue to keep his contact limited for the time being. As he mentioned Friday, his twisted back was unrelated to the lower back surgery that resulted in an abbreviated 2014 rookie season. Once he's cleared for all activity, he'll commence building up his expected pass-catching role out of the backfield.
