The Vikings signed fourth-year quarterback Brad Sorensen on Saturday.

Sorensen, 28, has not appeared in a NFL game. He was a seventh-round pick by the San Diego Chargers three years ago and has also spent time with the Tennessee Titans. Sorensen (6-5, 230) last played a year ago in the preseason, completing 38 of 69 passes for 336 yards, one touchdown and three interceptions.

The move comes two days after starting quarterback Teddy Bridgewater was a surprise sit for a preseason game in Seattle. He's reportedly dealing with a sore shoulder, which led to backup Shaun Hill starting the game. Hill completed 10 of 17 passes for 129 yards in the Vikings' 18-11 exhibition win.

The Vikings' quarterback depth initially took a hit when last year's third-string passer, Taylor Heinicke, showed up to camp with a torn tendon in his foot. He's expected to start the season on the non-football injury list.

Running back Kevin Monangai was waived in a corresponding move.
