Head coach Pete Carroll indicated Monday the team is "very optimistic" Chancellor (groin) can return to action this week, Liz Mathews of ESPN reports.
Chancellor has missed the previous two contests for Seattle as he has dealt with a groin injury. While his status should continue to be monitored throughout the week, he appears to be trending toward a return Sunday. Kelcie McCray has filled in at strong safety in Chancellor's absence.
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.
