How is Shamrock.. injury wise?? I think that is the only thing that could cause him to lose.
When was this fight announced? How much training have they had...
Shamrock is fine injury wise. He broke his arm in his fight against cung le over a year ago. And the fight was announced probably 2.5-3 months ago, which is plenty of time to train (most fighters usually have 6-8 week training camps).
