The centre-back is said to be keen on a move away from Ewood Park this month amid speculation that he refused to play against Fulham yesterday afternoon.
Tottenham Hotspur have also been credited with an interest in the 27-year-old, but it is QPR who have submitted the first bid.
"It's common knowledge we've put in a bid for Chris Samba," Hughes told Sky Sports News.
"We have a number of players we would like to bring to the club. We'll have to wait and see."
Hughes signed Samba during his spell in charge of Blackburn.
