Mike Tomlin said today that Emmanuel Sanders had his knee scoped and will be out until after the bye.
Daniel Sepulveda also had surgery to repair a torn meniscus in his knee, but he's already been placed on injured reserve.
Hines Ward is OK after suffering from "concussion-like symptoms" following an illegal helmet-to-helmet hit by Ray Lewis that was not flagged during the game.
They'll watch Ward this week to determine his status for Sunday's game at Cincinnati.
LaMarr Woodley could possibly return this week, but there's a better chance James Farrior comes back.
If Farrior returns, Lawrence Timmons could be moved to left outside linebacker - where he lined up at times Sunday - with Farrior and Larry Foote inside.
Wide receiver Jerricho Cotchery is experiencing some swelling in his knee, but is expected to be OK.
