http://mmaweekly.com/strikeforce-working-really-hard-to-make-fedor-vs-hendo-happen Both fighters have contracts with Strikeforce. There is a possibility that the M-1 team is looking for a loophole in Fedor's deal that would allow a renegotiation in order to get a PPV share. The loophole is that perhaps Fedor is contracted to fight at heavyweight but a catchweight fight would be separate from his existing deal.
lol this is ridiculous. Definitely something suspect about M1 demanding a catch weight when Hendo is willing to fight at HW where Fedor wouldn't have to worry about weight at all.
TBH I understand where M-1 is coming from but if they are trying to co-promote a PPV with Strikeforce that might be an uphill battle (given Zuffa's acquisition).
