A girl on my HS team once got dq'd in the 4x100 ( i actually think a similar thing ahppened at the NCAA champsionships a few years back) for wearing a different colored sports bra... these bullshit rules are there just for bitches like Knowles. I don't understand why she couldn't jump again??? Since the vault allows for 3 attempts per height, i would think that only the jump would be thrown out... but i guess not.
