It is believed both Fulham and Leicester are pursuing loan deals for the 20-year-old ahead of the new year after a slow start to the season which has seen him make just 9 appearances so far under manager Fabian Hurzeler.
Last season the Ireland international made 36 appearances, scoring 6 and assisting 1 in an impressive season for the young striker.
Both Fulham and Leicester City are searching for a striker this January to help freshen up their attack which is currently ageing with the likes of Jamie Vardy and Raul Jimenez up top.
Burnley are also reportedly interested in Ferguson but reports suggest he is believed to prefer a switch to a fellow top-flight club as opposed to dropping down to the Championship.
