According to a report on MMAjunkie.com, brothers Jim Miller and Dan Miller have both signed exclusive four-fight contracts with the UFC.
Both Millers had valid contracts with the IFL, with Dan Miller holding the promotion’s middleweight title. This site reported last week that the UFC was in the process of acquiring the IFL, but an acquisition had yet to be finalized.
To date, no official statement about a possible acquisition has been made by the UFC or the IFL so it’s uncertain how the UFC could reach a contract agreement if at least limited assets had not been acquired.
I suspect it's a lot more than limited assets. The fact that while folks like Chris Horodecki have been saying the IFL has allowed their talent to roam while they settle matters internally, the truth is these folks are gone. There's no way the UFC allows these fighters to return to the IFL should that organization miraculously straighten out it's finances. More importantly, would they even want to return?
As for the Miller brothers, they are exciting additions to the middleweight and lightweight line-ups in the UFC. I doubt they are world beaters, but they are a handful for anyone at those weight classes. Good signing by the UFC.
