Rovers are pursuing out-of-favour Leicester City striker Martyn Waghorn, the Free Press understands.
But hopes of securing a deal before the end of the January transfer window have been hit by Leicester’s determination to recoup money for the forward.
Waghorn is out of contract in the summer and is set to fall further down the attacking pecking order at the King Power Stadium this week with Leicester expected to announce the signing of Kevin Phillips.
The Foxes are nevertheless determined to recoup a significant chunk of the reported £3m they paid Sunderland for the striker in 2010 with a figure approaching £500,000 allegedly quoted.
Such a figure is beyond Rovers, who would prefer not to deal with any transfer fees.
The asking price is said to have also put off other suitors for Waghorn’s signature.
Should Leicester be unable to secure a permanent deal for Waghorn during January, they will allow the 23-year-old to leave on loan.
Paul Dickov has strong connections with Leicester and could put them to use in order to arrange a loan deal.
Waghorn spent the last three months of 2013 on loan at Millwall, who are reportedly keen on a permanent deal.
Sheffield United have also been linked with the former England U21 international and boss Nigel Clough has refused to rule out a move.
Waghorn has not started a game for Leicester in more than 13 months and has made just 24 starts since his summer 2010 switch.
He netted three times during his loan spell at Millwall.
