The Detroit Lions have acquired quarterback David Blough and a seventh round pick in 2022 in exchange for Detroit's seventh-round pick in 2022, a source told ESPN Insider Adam Schefter. This marks the fourth straight year that general manager Bob Quinn has made a trade in the preseason or at the cutdown deadline. This particular deal is intriguing because the Lions signed quarterback Luis Perez earlier this week as a potential practice squad quarterback and also have veterans Tom Savage and Josh Johnson on the roster as potential backups to starter Matthew Stafford. Blough's name is now thrown in that mix after the Lions saw him play Thursday night in the preseason finale when they faced the Browns. It could mean the Lions are considering keeping three quarterbacks (perhaps a veteran and Blough) or made the deal at essentially no cost to just have another option before 4 p.m. Saturday.
