The UFC's attempt at two events in one day isn't off to the cleanest of starts.
If you're wondering why there are no advertisements on the canvas of the UFC Fight Night: Mousasi vs. Munoz card in Berlin, it's because the canvas they intended to use is currently in Brazil for the TUF Brazil 3 Finale. UFC president Dana White responded to the question of "why aren't there ads?" with this gem on Twitter:
So instead, we're left with a Berlin canvas that just features the UFC logo and nothing more. Yes, someone indeed "f**ked up BIG", and when you watch the TUF Brazil 3 Finale later this evening you'll be viewing the ad-laden canvas you otherwise would've seen in Germany today.
In the bigger picture, the average fight fan doesn't really care, but it's something noteworthy to pass along.
