Because the fight is at 175 not 170.
I just read something about Royce saying he didn't want to make 170.
the 175 is just a safty thing to make damn sure hughes doesnt lose the title to someone that will leave... AGAIN!
yeah, its like an exibition match
"White says the Matt Hughes-Royce Gracie fight is a non-title affair because Gracie did not want to make the 170-pound weight."
