Bolton Wanderers strikers Ivan Klasnic and Kevin Davies could be on the move this month.
The Daily Mail says Bolton's move for Philadelphia Union striker Sebastien Le Toux has cast doubt on the futures of Davies and Klasnic.
Klasnic has attracted interest from Wolves and Wigan but is reluctant to swap one relegation struggle for another.
Wolves are also keen on Davies, although Coyle insists he still has a role to play at the club.
