Stout (shoulder) is active for Sunday's game against the Falcons, Brooke Evans of the 49ers' official site reports.
Stout is nursing an AC sprain in his shoulder, but the second-year defensive back has been given the green light to play in Sunday's contest. He has 18 tackles (11 solo), including 0.5 sacks, and one pass defense through the first six games of the regular season.
