The 25-year-old scored 12 goals in 32 Premier League appearances last season, but failed to save the Black Country outfit from the drop.
Reports suggest that Wolves, who have appointed Stale Solbakken to succeed Terry Connor as boss following their relegation, want as much as £15m for the Scot.

However, the Black Cats are prepared to test their resolve again after having a £10m bid rejected, as manager Martin O'Neill looks to bolster his squad ahead of his first full season in charge on Wearside.
Wolves chief executive Jez Moxey recently insisted that the club's best players are not for sale this summer, though Solbakken has admitted he is open to the prospect of Fletcher leaving alongside the highly rated Matt Jarvis.
