A pair of rematches most of the MMA world has been salivating over finally go down this week at UFC 168, the promotion’s year-end show.

Here’s the essential information for the card.

UFC 168 START TIME: UFC 168 takes place Saturday at MGM Grand Garden Arena in Las Vegas. The event kicks off with two prelims on MMAjunkie (as well as Facebook and Youtube) at 7 p.m. ET (4 p.m. PT), followed by four more prelims on FOX Sports 1 (8 p.m. ET) and the five-fight main card at 10 p.m. ET on pay-per-view.

UFC 168 BACKGROUND: In July, Chris Weidman (10-0 MMA, 6-0 UFC) ended the long reign of Anderson Silva (33-5 MMA, 16-1 UFC) atop the middleweight division and pound-for-pound rankings with a stunning second-round knockout at UFC 162 in Las Vegas. Silva was widely criticized after the loss by some saying clowning around in the cage led to him getting caught by Weidman. Although UFC President Dana White ultimate would defend Silva’s style as something he’s always done, but just didn’t have go his way this time, he quickly ordered a rematch. The card also features a second title rematch. Women’s bantamweight champion Ronda Rousey (7-0 MMA, 1-0 UFC) defends her title against the woman she took it from nearly two years ago in Strikeforce, Miesha Tate (13-4 MMA, 0-1 UFC). The two heated rivals are coming off coaching stints opposite each other on Season 18 of “The Ultimate Fighter,” and the phrase “no love lost” may have been coined just for them.
