UFC President Dana White announced on Saturday that the rematch between Anderson Silva and Chris Weidman will be on December 28 in Las Vegas.

Silva suffered a stunning loss–and lost his UFC Middleweight title–last week when he got knocked out while showboating in the second round. The Silva-Weidman rematch will be the co-main event with Ronda Rousey vs. Miesha Tate II for UFC 168. 

White made the announcement on ESPN’s SportsCenter.
