For all the accolades she has earned, and the press that has been heaped on her, there is also basic math to understand: She's No. 2 in another category.

The first female fighter to enter the octagon as a combatant in a UFC event will be . . . Liz Carmouche.

-- Carmouche was born in Lafayette, La., and raised in Okinawa, Japan. She now lives and trains in San Diego, Calif.
