Memorial Day weekend 2015 is lined up to be a massive pay-per-view card for the UFC. Headlining UFC 187 on May 23rd is a light heavyweight championship showdown between Jon Jones and Anthony Johnson, while the co-main event is the rescheduled middleweight title affair between Chris Weidman and Vitor Belfort. The fights were made official on Wednesday's edition of UFC Tonight on Fox Sports 1.

Jones (21-1) started 2015 with a unanimous decision win over the previously unbeaten Daniel Cormier in the main event of UFC 182. The win then took a back seat to controversy when it was revealed that he had tested positive for cocaine metabolites prior to the bout. Jones was fined $50,000 by the UFC for violating the promotion's code of conduct. Johnson (19-4) is coming off a stunning 1st round TKO over Alexander Gustafsson in the main event of UFC on Fox 14 in Gustafsson's backyard in Sweden. "Rumble" is 3-0 since his UFC return last year, and he's a perfect 7-0 at light heavyweight.

Weidman (12-0) has defended his middleweight strap twice, beating Anderson Silva in their December 2013 rematch and then edging out Lyoto Machida in a thrilling UFC 175 main event in July 2014. Injuries have twice forced Weidman to pull out of scheduled meetings with Belfort, once at UFC 181 and then again for 184. Belfort (24-10) forced the delay of the first planned date between the two fighters after failing a random drug test last February. The outright ban on TRT would soon follow, but Belfort still kept his spot at the front of the line. Assuming this fight doesn't get cancelled again, it will be more than two years since Belfort's last appearance at middleweight (a 1st round TKO of Luke Rockhold), and 18 months since his 1st round KO of Dan Henderson.

UFC 187 also is the landing spot for a #1 contender lightweight bout for Donald Cerrone and Khabib Nurmagomedov. No doubt that the UFC is going all-out on this holiday weekend, and hopefully these top 3 fights stay intact come May 23rd.
