The Bears signed Barkley to the practice squad Sunday, Adam Schefter of ESPN reports.
In advance of Week 1 last season, the Cardinals dealt for Barkley with the aim of developing him within head coach Bruce Arians' system. While Barkley received negligible reps during the regular season, the offseason was a different story, and he proceeded to complete at least two-thirds of his passes in the last three preseason games. However, it wasn't enough to stick in Arizona. After his release Saturday, the Bears have decided to inquire about the 2013 fourth-round pick.
