Chancellor (groin) was a non-participant at Wednesday's practice, John Boyle of the Seahawks' official site reports.
Head coach Pete Carroll indicated that the Seahawks would have to see how Chancellor makes it through the week before determining his game status. As such, Chancellor will likely need to practice in some for another to be considered healthy enough to play, so stay updated with his progress as the week goes on. The Seahawks could sure use the hard-hitting safety against an explosive Saints' passing attack.
Pierre-Louis (ankle) will not play in Sunday's game against the Cardinals, Curtis Crabtree of UPI.com reports.
This will be the first game missed for Pierre-Louis this season. He provided a season high three tackles in last Sunday's win over the Falcons. Dewey McDonald and Jordan Tripp figure to see an increased workload providing depth at outside linebacker while Pierre-Louis is sidelined.
Rawls (leg) is scheduled to run this week with the expectation that he can play Week 9, coach Pete Carroll said at his Monday press conference.
Rawls has been out since suffering a hairline fracture in his left fibula in Week 2. The Seahawks running game could use a boost with Rawls' return. The Seahawks will bring him along slowly, though, so Week 9 might be best-case scenario.
Willson (knee - MCL) responded well to surgery and is hopeful to return this season, ESPN's Liz Mathews reports.
Willson injured his knee Sunday against the Falcons and went under the knife Tuesday in order to fix it. He's slated to miss multiple games, but it seems he could realistically return later on in the season.
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.
