It turns out not even the best fighters in the world enjoy having machinery in their mouths.

The UFC is having its first pay-per-view of 2017 this Saturday night (Feb. 11) inside the Barclays Center in Brooklyn, NY. The headliner for that card features the inaugural women’s featherweight title match-up between Holly Holm and Germaine de Randamie.

Slotted in as the co-main event are middleweight great Anderson Silva and Derek Brunson. Speaking of Silva, he got episode three of UFC 208 Embedded started by getting his mouthpiece fitted. It was not a very pleasant experience for “The Spider” to say the least.

Here is the description of this episode from the official YouTube channel of the UFC:

“On Episode three of UFC 208 Embedded, former middleweight champion Anderson Silva gets fitted for a mouthpiece. Featherweight title contenders Holly Holm and Germaine de Randamie arrive in Brooklyn and acclimate to the city.
