UFC 168 takes place on Saturday night in arguably the biggest night of the year for MMA fans as the rematch of Chris Weidman and Anderson Silva takes place. The fight card also features a mouth-watering match up between Ronda Rousey and Miesha Tate.

The event gets underway on UFC.com with the online preliminary fights taking place from 7 p.m. EST. The online prelims will feature William Macario vs. Bobby Voelker, and Robbie Peralta vs. Estevan Payan.

At 8 p.m. EST the main preliminaries will take place on Fox Sports 1, and features four big match ups for MMA fans to watch including Chris Leben vs. Uriah Hall, Gleison Tibau vs. Michael Johnson, Dennis Siver vs. Manny Gamburyan, and John Howard vs. Siyar Bahadurzada.

Those 6 preliminary fights will lead up to the main card, which features five big fights.

Poirier will take on Brandao before Miller and Camoes take to the Octagon. Building up to the main events, Barnett will take on Browne, before co-main event Rousey and Tate take to the stage.

The main event will feature undefeated Chris Weidman against experienced Anderson Silva, with Silva looking to gain revenge for his loss to Weidman earlier this year in a shock result.

Weidman's knock out of Silva earlier this year turned many heads in the UFC, but many were not convinced believing it to be somewhat of a fluke. However, Weidman has not backed down and wants to silence his critics by defeating Silva for the second time in 2013.
