Aston Villa and Newcastle United are among several sides interested in the Fulham star.
The Cottagers have rigidly stuck to that price as a selling point this summer amid widespread interest in the Scotland international.
Newcastle United, Aston Villa, Norwich City, Hull City and Sheffield Wednesday all have an interest in his services, but so far have been put off by the asking price.
Fulham boss Slavisa Jokanovic needs funds to try to turn the squad into one that can challenge for promotion and sacrificing McCormack would allow him to do so.
However, they have struggled to find a buyer at that previous £12 million release clause and may have to change their stance once that clause ends on Friday according to the Daily Mail.
The expiry of that clause opens up the possibility of negotiation over the fee and those previously interested clubs may do just that to get their man at a price more to their liking.
Whether Newcastle are among them though remains to be seen given they are allegedly close to completing a deal for Crystal Palace forward Dwight Gayle.
