Shoulder surgery recovery complicated by serious criminal charges carrying life sentence.

Arnold suffered a shoulder injury requiring season-ending surgery that limited him to eight games last season and forced him to compete for a starting spot in training camp this summer; however, his NFL availability is now in severe jeopardy due to legal charges—he faces four counts of kidnapping and four counts of armed robbery stemming from an alleged kidnapping and robbery plot in Tampa in February, with prosecutors alleging he was the primary conspirator; the charges carry a potential sentence of up to life in prison, and he is being held without bond, creating significant uncertainty around his playing time and roster status.
