The UFC's annual year-end event is traditionally a good one, and 2013's UFC 168 is no exception. All things considered, Saturday night's card may very well be the best of the year.

The show gets underway at 7 p.m. ET online, before heading to Fox Sports 1 at 8 p.m. ET and then settling in for the main card on pay-per-view at 10 p.m. ET.

Headlining the event is, of course, a highly anticipated pair of championship rematches. The co-main event of the evening will see bitter rivals Ronda Rousey and Miesha Tate square off, while the main event proper will feature a showdown between the legendary Anderson Silva and the current UFC middleweight champion Chris Weidman.
