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.
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.
Anthony (hamstring) has been ruled out for Sunday's game in Kansas City.
A late-week addition to the injury report, Anthony likely get hurt at practice either Thursday or Friday. It's not much of a loss for the Saints, as last year's second-round selection has only played 55 defensive snaps all year.
Breaux (leg) went through position drills Monday and hopes to return soon, ESPN's Mike Triplett reports.
Breaux broke his leg in Week 1, but he's already back to working out on the field with his teammates, showing just how well his rehab is going. Although it's unclear when Breaux can be expected to return to game action, the much-maligned Saints defense will certainly welcome having its top cornerback available again soon.
Lasco (hamstring) has been ruled out for Sunday's game in Kansas City.
Lasco has only logged 16 offensive snaps all season, but his 100 snaps on special teams are tied for third-most on the Saints. His versatility could eventually lead to more opportunities on offense, as he figures to stick around on the roster.
The Saints released Brown (calf) with an injury settlement Thursday, removing him from injured reserve, the New Orleans Times-Picayune reports.
Brown joined the Saints in May, adding a veteran presence to a receiving corps lacking in experience. However, he failed his pre-training camp physical due to a strained calf, which will bring his brief tenure in New Orleans to a close. The severity of the injury will likely determine when he receives a chance with another organization.
