As of Tuesday evening, it looks like QB depth will not be a problem for the Cards.
The Chicago Bears announced his release and Glennon reportedly has a new two-year contract with Arizona. The team chose to turn to young Mitchell Trubisky, whom they selected with the second overall pick in the 2017 National Football League draft, and took over as the starter for the remainder of the year.
In Chicago, the 28-year-old Glennon played in four games to begin the 2017 season after inking a three-year deal worth $43.5 million last offseason.
Glennon led the Bears to a 1-3 record as the team's starter and threw for four touchdowns and five interceptions, while also losing three fumbles.
However, for his career, Glennon has thrown 34 touchdown passes to just 20 interceptions.
With the Cardinals intending to sign Sam Bradford, Glennon would be poised to back up Bradford.
New Cardinals head coach Steve Wilks has said the team plans to be aggressive in pursuing its quarterback of the future, via free agency, a trade and/or the NFL Draft.
