Hall (ankle) has been ruled out for Thursday's matchup against the Packers, NFL Network's Mike Garafolo reports.
News came earlier in the week that Hall's ankle injury would not require surgery, but the rookie cornerback will be out for at least Week 7's tilt, with his next opportunity to return coming Week 8 on Monday night against the Vikings. Sherrick McManis and Cre'von LeBlanc could be in line for additional reps when the Packers deploy multiple-receiver offensive sets, but their roles likely won't be affected too severely if Tracy Porter (knee) and Bryce Callahan (hamstring) are able to play.
Ferguson has been handed a four-game suspension for a violation of the NFL's policy on performance-enhancing substances, Jeff Dickerson of ESPN Chicago reports.
After notching three tackles in four games, Ferguson was placed on season-ending injured reserve in October due to a nagging knee injury. Thus, his ban won't kick in until he's healthy enough to take the field during the 2016 campaign.
Gabriel (concussion) is expected to be able to return for Week 8's game against the Packers, ESPN's Vaughn McClure reports.
Gabriel hasn't practiced this week due to his concussion, which will certainly see him miss Sunday's game against the Chargers. However, coach Dan Quinn anticipates Gabriel's absence to be relatively short-lived, as he should be back available next weekend. While Gabriel's progress through the league protocol will ultimately determine whether that timetable is realized, Justin Hardy and Aldrick Robinson should split his vacated snaps in the meantime.
