The Vikings made a roster move Tuesday involving a former quarterback.
Tackle Carter Bykowski, an Eden Prairie native, re-signed onto the practice squad. The team released cornerback Tre Roberson, a former college quarterback, with the corresponding move.
Bykowski, 26, spent last season on the Vikings injured reserve list with a torn pectoral muscle. He was a 2013 seventh-round pick by San Francisco out of Iowa State. The Vikings originally signed Bykowski off the 49ers practice squad in December 2014.
His addition comes a day after two reserve offensive linemen, Jermiah Sirles and Nick Easton, were unable to practice Monday due to undisclosed injuries.
