The Minnesota Vikings are searching for a backup quarterback, and it originally looked like Sean Mannion would be the man for the job after meeting with the Vikings on Sunday.

However, Mannion left Minnesota without a deal, meaning that the team's search for a second-string signal-caller will continue, according to Chris Tomasson of The St. Paul Pioneer Press.

Mannion, who played his collegiate football at Oregon State University, was originally selected by the St. Louis Rams in the third round (89th pick overall) of the 2015 NFL Draft.

He spent all of his first four seasons with the Rams, playing in 10 games and making one start. Overall, he completed 33 of his 53 passes for 258 yards and an interception.

Now, with the Rams going with Blake Bortles as their backup to Jared Goff, Mannion is looking for a new home.

The Vikings lost their own second-string quarterback, Trevor Siemian, in free agency to the New York Jets last month. They still do have Kyle Sloter, so if worse comes to worse, Minnesota could slot Sloter in as the primary backup behind Kirk Cousins, but it appears that Minnesota is looking for some security.

The Vikings are coming off of a disappointing 2018 campaign in which they went 8-7-1 and missed the playoffs, one year after winning 13 games and making it all the way to the NFC Championship Game.

Success in back-to-back years has been a hard thing for Minnesota to come by in recent years, as the Vikings have not made back-to-back postseason appearances since 2009.
