Former Nebraska quarterback Tommy Armstrong is back on the free agency market.

The Minnesota Vikings announced Friday morning that they had waived Armstrong, who was trying to make the transition to safety with the NFL franchise.

Armstrong had originally arrived in Minnesota as a running back, however was moved to safety during the final day of camp. The undrafted free agent impressed enough to be initially invited back for OTAs, however that offer was rescinded following roster number complications. Armstrong was later signed by the Vikings, but will now be moving on.

Prior to signing with the Vikings, Armstrong had free agency interest from several teams.
