Could Patrick Peterson be on the sidelines for the game on Saturday?

The Cards last preseason game, i think is thursday. So he'd have over a week before their first game, would he have any down time to go be on the sidelines for the game? Ive seen plenty of former players go back to their college teams and stand on the sidelines with the team. I think with everything thats happened you could never have too much moral support. He could still give advice and support. Just because hes not in a tiger uniform anymore doesnt mean he cant still be a leader
