Hopkins (hamstring) is listed as active Thursday against the Packers, Darren Urban of the Cardinals' official site reports.
Hopkins was considered a game-time decision after not practicing on a short week of prep due to a hamstring injury. Following a pregame warmup, though, he'll be available to Arizona's offense versus a Green Bay defense that will be without Week 1 starting cornerbacks Jaire Alexander (shoulder) and Kevin King (shoulder).
