Brown (hamstring) was activated from the non-football injury list Tuesday morning, Ian Rapoport of NFL Network reports.
Brown can now practice with his Cardinal teammates, after missing the first week of training camp due to a hamstring injury he reportedly suffered during a private workout over the summer. He may be eased into practice with his new team, as there's a high recurrence rate for soft-tissue injuries -- and perhaps even more so for speed-dependent players. Brown has nearly six weeks to ramp up before Arizona's season opener against Kansas City, at which point teammate DeAndre Hopkins will begin serving a six-game suspension.
