The biggest concern over the cancellation of UFC 151 was the status of all of the fighters scheduled to compete on the card . They had trained months to fight on September 1st and on August 23rd their work was seemingly put to waste. As of today the UFC has successfully rescheduled 7 of their 10 main and preliminary card fights, as well as the retooled main event of Jon Jones vs. Vitor Belfort instead of Jones vs. Henderson, Jones vs. Sonnen, or Jones vs. Machida. Here's a recap of which fight is going where as well as whether or not they've been placed on the main card or preliminary card.
UFC 152 (Sept. 22nd)
Jon Jones vs. Vitor Belfort (main event)
Charlie Brenneman vs. Kyle Noke (preliminary card)
UFC on FX 5 (Oct. 5th)
Jay Hieron vs. Jake Ellenberger (main card)
Dennis Hallman vs. Thiago Tavares (preliminary card)
Danny Castillo vs. Michael Johnson (preliminary card)
Shane Roller vs. Jacob Volkmann (preliminary card)
UFC on FUEL 6 (Nov. 10th)
Takeya Mizugaki vs. Jeff Hougland (unknown)
John Lineker vs. Yasuhiro Urushitani (unknown)
To Be Determined
Abel Trujillo vs. Tim Means
Daron Cruickshank vs. Henry Martinez
Dennis Siver vs. Eddie Yagin
According to Yagin and Tim Means, their fights are currently being rescheduled so those bouts will have official new homes very soon. Cruickshank vs. Martinez is not confirmed for anything right now.
On the topic of fighter pay, Eddie Yagin and Takeya Mizugaki did get their sponsorship money from Fear the Fighter. The others on the card were also offered show money or an immediate booking on an upcoming event by the UFC, according to Jason Kelly of MMADiehards.
The timing and circumstance obviously affected the type of event these fights would be moved to (and the UFC only have two total PPVs from October to November), but it looks like all of the scheduled main card fights for UFC 151 end up on free TV (except Jon Jones of course), with Hallman vs. Tavares dropping from PPV main card to the preliminary card of FX 5.
