Sorensen was a 2013 seventh-round draft pick of the San Diego Chargers and also spent time with the Tennessee Titans, whom the Vikings face in their regular-season opener.
Sorensen became the first ever NFL draft pick from Southern Utah when the Chargers selected him 221st overall in 2013. Prior to that, he had attempted to get playing time as a walk-on at BYU, but eventually transferred to Southern Utah in 2010.
There he completed 67 percent of his passes for 3,163 yards and 21 touchdowns as a sophomore and won All-Great West Offensive Player of the Year following a junior season in which he produced 3,143 yards and 17 touchdowns while completing 67.8 percent of his passes. As a senior, he threw for 23 touchdowns and 10 interceptions.
He hasn’t appeared in any regular-season games in the NFL.
To make room for him on the roster, the Vikings released RB Kevin Monangai.
QB Taylor Heinicke, who suffered a leg injury before training camp, remains on the reserve/non-football injury list.
