Because they only keep two quarterbacks on the 53-man roster, the Minnesota Vikings had taken to keeping their third quarterback on the practice squad. If they’re going to continue that strategy, they’re going to need to bring in someone else.
David Blough, who had been serving as QB3 for the Vikings for most of this season, has signed with the Arizona Cardinals for a spot on their active roster. The Cardinals just lost Kyler Murray for the season to an ACL tear, so Blough had an opportunity to go there and potentially be the backup to Colt McCoy.
