Left with only two quarterbacks after releasing Kellen Mond and Sean Mannion during roster cuts this week, the Vikings signed former Lions quarterback David Blough to their practice squad on Friday.
Blough, 27, was waived by Detroit on Wednesday. Like Nick Mullens, whom the Vikings acquired Aug. 22 and expect to be their backup, Blough has experience as an NFL starter. He started five games for the Lions as an undrafted rookie out of Purdue in 2019, including a 20-7 loss to the Vikings at U.S. Bank Stadium, but he has appeared in only two more games the past two years.
