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 (ankle) remains a few weeks away from his return, according to coach Pete Carroll, 710 ESPN Seattle's Liz Mathews reports.
Rawls has been sidelined since Week 2 due to a fibula injury and general manager John Schneider started October by projecting he'd need another month to recover. As a result, Carroll saying he's still a few weeks away fits that timeline, although Rawls still has no definitive date for his expected return. While that leaves his already-frustrated fantasy owners in further limbo, Rawls' absence figures to allow Christine Michael to continue to dominate Seattle's backfield workload, with rookie Alex Collins and C.J. Prosise (wrist) factoring in behind him.
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.
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.
