A Reading Football Club spokesman failed to deny the rumours. He told Reading Mad: "We do not wish to comment on the rumours linking us with a move for Steve Brown."
The Royals had been reportedly ready to sign Brown during the summer months. However, boss Alan Curbishley chose to keep him at the Valley.
Despite making three appearances so far this season it appears that Brown would be allowed to leave should Alan Pardew make a suitable bid for the player.
Pards maintains a good relationship with Charlton, one of his former clubs. Previously this has seen John Salako, Keith Jones and Ben Roberts (loan) join the Royals.
Brown has a year left to run on his current deal at the Valley.
