ANAHEIM, Calif. -- Ronda Rousey, the first female champion in UFC history, says she likely won't feel she's earned that distinction until she wins her first UFC fight.

Rousey (6-0) weighed in at 134.6 pounds Friday for her first UFC title defense against Liz Carmouche (8-2), who also made weight at 133.6 pounds. The two will fight Saturday night at UFC 157.
