On Friday, the Arizona Cardinals announced the release of backup quarterback Mike Glennon, leaving Josh Rosen and Charles Kanoff as the only QBs on the roster.
Glennon, 29, signed a two-year deal with the Cardinals last March. He appeared in two games last season and completed 15 of 21 passes for 174 yards and one touchdown.
