Falcons cornerback Jalen Collins, who started in the Super Bowl, was working with the third-team defense on Tuesday.
The former second-round pick from LSU was also on the special teams knit-cap/scout team.
Desmond Trufant and Robert Alford were working with the first-team.
C.J Goodwin and Deja Olatoye were working with the second team. Brian Poole was the first-team nickel back and Blidi Wreh-Wilson was the second team nickel back.
Collins took over for Alford at right cornerback down the stretch of last season after Trufant went out with a pectoral injury.
Alford moved over to left cornerback.
Collins played well and some projected that he was ready to contend for a starting position.
