Microsoft has announced that the UFC App on Xbox 360 has been delayed. The pay-per-view on-demand video content was originally slated for release tonight, but will instead be made available on December 20, which will features a match-up between Lesnar and Overeem. The next match on the docket is December 10, and is between Jones and Machida. No word on why the App was canceled last minute was provided at press time. Thanks, Shack.
