Boss Mick McCarthy says Town have received interest in one of their players and also loan enquiries regarding two other members of his squad.
"There has been a bit of interest, certainly in one of the players, and in terms of loans we have had enquiries about two others,” the Blues manager told the club site.
The loan enquiries are almost certainly from Rotherham regarding striker Kieffer Moore and right-back Josh Emmanuel, while the identity of the other player targeted is currently a mystery, although Wolves were recently eyeing left-back Jonas Knudsen.
Striker Brett Pitman and midfielder Kevin Bru are understood to have been told they can move on if they can find themselves new clubs over the summer.
