"Zero regrets. I’ve been getting better everyday and having so much fun with my new team. Focusing on controlling the things I can control. Yesterday was not one of those things! Thanks for the well wishes."Drafted 20th overall by the Bears&nbsp;in 2013, Long missed just one game over his first three seasons, and was selected to three consecutive Pro Bowls. He appeared in just 30 regular-season contests over his last four years with Chicago due to a variety of injuries.Long had been playing as the starting right guard during Chiefs workouts this spring.
