Skysports.com understand Wolves and Queens Park Rangers have had bids rejected for Southampton's Dexter Blackstock.
Crystal Palace and Sheffield Wednesday, along with Wolves and QPR, are thought to be chasing Blackstock.
The arrival of Bradley Wright-Phillips at Southampton has increased competition for places at St Mary's and suitors of Blackstock are hoping the South Coast club may be willing to let the forward leave.
Queens Park Rangers boss Gary Waddock has previously expressed his interest in Blackstock and he followed that up with a firm bid which was rejected by Southampton.
New Wolves manager Mick McCarthy is also looking to add to his striking options and tabled an offer for Blackstock.
Southampton are in no rush to let Blackstock go and are holding out for their full valuation of the player.
