The Vikings have signed Augustana RB C.J. Ham, who participated in last weekend's rookie minicamp, to the 90-man roster. To make room the club has waived S John Lowdermilk.
Ham, a Duluth native, was named an All-NSIC South Division Second Team player in 2015, rushing for a career-high 1,097 yards and 16 touchdowns, leading the Northern Sun Intercollegiate Conference in both catagories.
