Perkins won't play against the Los Angeles Clippers on Wednesday at Staples Center, nor against the Golden State Warriors on Thursday night in Oakland, league sources told Yahoo Sports.

Steven Adams is expected to replace Perkins in the Thunder's starting lineup. Adams, a rookie, has cut into Perkins' minutes this season. Perkins, 29, is averaging three points and nearly four rebounds in 18.3 minutes per game.
