A suspected brain injury from 14 years of playing football, a positive attitude and the support of a treatment center director led a federal judge to impose a no-prison sentence Thursday for former Arkansas Razorback Cedric Cobbs.

Cobbs, 35, who left Arkansas in 2004 to join the National Football League, where he was a running back for the New England Patriots and the Denver Broncos, also had the support of a federal prosecutor who told the judge that Cobbs was a minor player in a prescription pain pill conspiracy.
