I'm not too over the moon about this card either, but sometimes these are the ones that turn into the best.
However, I also think it should be a free fight....just not enough relevent star power. Seems like these fights are really just put together to see where these fighters stack up in their division.
The questions are: Does Rampage still want to fight? Is Rick Story for real? Does Big Country have what it takes to make a run for the belt?
In regards to injuries and fight pull outs, I think this is just a byproduct of Zuffa offering insurance to fighters who get injured in training.
All that being said:
Hammill by decision
Mir by decision
Story by KO
