Incidentally, just as a footnote to this topic: I did get a response from Five USA clarifying their position on the matter.
Thank you for your recent enquiry regarding The Ultimate Fighter: Heavyweights.
Unfortunately, we are not in a position to transmit live coverage of the Series 10 finale tomorrow, 5th December. As you may be aware, the event is due to start in Las Vegas at 15:55 local time and Five USA ceases transmission at 01:00 GMT. This means that a live programme would only have been broadcast for approximately one hour.
The terms of our contract require the programme to be broadcast on Five USA and we are therefore unable to transmit the finale live on Five.
Nevertheless, your disappointment that our coverage will be delayed has been noted in our Viewer Enquiries Report. This is circulated throughout the company and will be seen by all relevant personnel.
Not to worry, as was reported earlier, it will now be available live on ESPN UK.
