Dixon left Saturday's preseason matchup with an apparent chest injury and is questionable to return, Jonathan Jones of the Charlotte Observer reports.
In his NFL debut last week, Dixon tallied three tackles against Baltimore. The Washington product has taken reps at both cornerback and safety for Carolina in the early going, but with a lot of uncertainty surrounding Dixon and his injury, it remains to be seen if he'll be able to squeak onto the roster by preseason's end.
Webster remains out of practice with a lingering hamstring injury, Joe Person of the Charlotte Observer reports.
Webster pulled his hamstring nearly two weeks ago, so it's a bit concerning that he's still dealing with some lingering pain. He remains without a concrete timetable for a return and appears doubtful for the team's preseason matchup with the Titans on Saturday. Webster is a projected depth option at defensive end for the upcoming season and will need to get back to full strength if he wants to avoid falling any lower on the depth chart.
Johnson (Achilles) was placed on the Panthers' reserve/NFI list on Monday, Steve Reed of the Associated Press reports.
Johnson also began training camp on the active/NFI list after undergoing offseason surgery to repair an Achilles injury suffered last season with the Patriots. Although no timetable was provided for his return, Johnson could theoretically resume playing after the first six weeks of the regular season.
Jones (calf) said he will play Monday against Saints, according to ESPN's Adam Schefter.
Jones missed practice earlier in the week, and while he put in only a limited effort Saturday, it was apparently enough to give him confidence to play Monday. His presence would certainly be a huge boost against a Saints defense that is one of the worst in the league.
Worrilow (groin) underwent surgery on Thursday and is expected to be sidelined for at least four weeks, Vaughn McClure of ESPN.com reports.
Worrilow, the Falcons' leading tackler the past three seasons, was replaced by rookie Deion Jones in the starting lineup this season and has yet to record a stat this season. Philip Wheeler will move back to inside linebacker with the linebacking core thinned out due to Worrilow's and De'Vondre Campbell's (ankle) current injuries. The Falcons also signed O'Brien Schofield on Wednesday to give the team a little added depth for Week 3's tilt with the Saints.
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.
