Vannett (ankle) was a limited participant at Wednesday's practice, Bob Condotta of The Seattle Times reports.
Vannett has now been limited in two straight practices, which is a sign that he is making progress with his recovery from an ankle sprain. When he does return to game action, he will sit behind Jimmy Graham and Luke Willson at tight end and is unlikely to make any kind of fantasy impact.
Collins tallied 17 total tackles in 16 games during his rookie year with the Falcons.
Collins was limited to rotational work, only seeing the field on 28.6 percent of the total defensive snaps. He'll likely earn more playing time in the coming years, but the Falcons have a pretty young core of secondary players, meaning it won't be easy for Collins to ascend the ranks.
