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.
Eifert (back, ankle) is officially listed as questionable for Sunday's game against the Browns.
Though the tight end was listed as a full participant in Friday's walk-through, coach Marvin Lewis fell short of either declaring Eifert either good to go this week, or out for Sunday's game. Fortunately for those holding out hope that Eifert might make his season debut this weekend, the Bengals kick off at 1:00 ET on Sunday.
