The former Leeds striker's big-money move south is reportedly being looked at by the FA - although the Scot is said to have done nothing wrong.
Fans have poked fun at the striker costing more than several big-name Premier League forwards but his goals have kept Fulham in the Championship - just like they did for Leeds the previous season - while his overall play has been phenomenal for the west London side.
McCormack's transfer away from Elland Road, however, is being investigated by the FA, say the Mirror, although the Scot himself is not said to have done anything wrong.
Indeed, claims have been made that Leeds owner Massimo Cellino 'sanctioned £185,000' in the way of a 'backhander' as part of the deal.
Cellino's response, as quoted by the Mirror, was: "Everything I done, for me, was clear. I had the club consultant and my accountants. I don’t know many people in England, if I did something wrong I didn’t do it on purpose."
The report comes a day after news broke from the Yorkshire Evening Post that the loan signing of Brazilian youngster Adryan is also being investigated by the FA. The Mirror have also offered the same line in their McCormack - Fulham story.
As promised, the Championship campaign has only been over for a few days and it's fireworks at Leeds...
