The Vikings continued to augment their roster in free agency on Sunday, adding another quarterback to back up Kirk Cousins in 2019.
According to an NFL source, the team is signing former Rams quarterback Sean Mannion to a one-year deal, bringing in the 2015 third-round pick to work behind Cousins this season. Mannion, who's played in 10 NFL games and started one over the past four seasons, had visited the Vikings in late March, and joins the roster as the team's most experienced option behind Cousins.
He'll try to hold the No. 2 job over Kyle Sloter this season, as the Vikings remake their QB depth chart following Trevor Siemian's departure to the Jets.
