Minnesota Vikings running back C.J. Ham has been lining up at fullback during the team’s 2017 rookie mini-camp. The Duluth native broke into the NFL last season as a tailback.

Ham was on the Vikings practice squad in 2016 and was briefly on the active roster but did not play in a regular season game, making him eligible to participate in this season’s rookie camp. Vikings Team Reporter Eric Smith wrote on Vikings.com today that during team drills Ham “lined up as a fullback in front of Vikings rookie Dalvin Cook.”

The Minnesota Vikings announced today rookie running back C.J. Ham of Duluth has been signed to the team’s 53-man roster.

Ham joined the Vikings during rookie camp on a tryout basis and signed to the practice squad after final roster cuts. He played high school ball at Denfeld, graduating in 2011. At Augustana College in Sioux Falls, S.D., he totaled 2,662 rushing yards, 949 receiving yards and 35 total touchdowns in 43 games.

Minnesota (7-7) visits Green Bay (8-6) on Saturday.
