Pardew is low on central defenders, and with Reading manager Steve Coppell stating that Sodje and Southampton's Alan Bennett may have to return because of the African Nations Cup, he could face a defensive crisis.
This means that January could be a very interesting month at The Valley, which could see a lot of comings and goings, especially in the loan market.
One loan deal that could take place is the return of Arsenal midfielder Alexandre Song, who played for The Addicks in the run-in of last season.
