I read a post from Cuban elsewhere and he said this fight was delayed becuase they are working on getting the details ironed out for a Major headliner for the event. I'm guessing maybe Fedor.
Quote from Mark Cuban:
I have a source that says the guy is full of shit.
we are accelerating our efforts with HDNet Fights. Not pulling back.
The only thing we havent set yet is our next fight. We had hoped to do feb15 or in March, but there is a fight we want to facilitate, but we have to get contractual clarification first. We thought this fight would be an amazing headliner, so its worth waiting for.
In the meantime we are working with our partners to get more and more live fights on HDNet and to expand our MMA programming.
When we come back with our next HDNet Fights card, like our last one it will be bigger and better than the one before it.
In the future, rather than wondering about "sources", all anyone has to do is ask me
PS it is indeed Mark Cuban on Sherdog, just read his past post history.
