Chad Mendes has a huge fight booked this Saturday at UFC Fight Night 63, as the featherweight will take on fellow contender Ricardo Lamas, in the main event.

Not only is it a big fight because Lamas is a ridiculously dangerous dude, but because Mendes is coming off his second loss to the champ, Jose Aldo. If Mendes wants to challenge for the title again, anytime relatively soon, a win on Saturday is a must.

In advance of this weekend’s bout, the UFC has posted a “Why I Fight” segment featuring the powerful wrestler, which you can watch below.

UFC FN 63 will be hosted by the Patriot Center in Fairfax, Virginia.
