Ellerbe (quadriceps) is inactive for Sunday's game against the Panthers, Josh Katzenstein of the New Orleans Times-Picayune reports.
Ellerbe is still awaiting his season debut while he continues to recover from the quad injury. He wasn't able to practice at all this week, so it's difficult to pinpoint when exactly Ellerbe might be back.
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.
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.
