Photos: UFC 168, women fighting, and a broken leg

Chris Weidman defended his UFC middleweight title when Anderson Silva apparently broke his left leg on a kick in the second round, ending UFC 168 with a horrific injury Saturday night in Las Vegas. Ronda Rousey retained her bantamweight title in the UFC's year-end event, submitting Miesha Tate with a third-round arm bar. Rousey then walked away from her bitter rival's offer of a post-fight handshake, earning ferocious boos from the MGM Grand Garden crowd.
