Who are these masked fighters? Check out the UFC on ESPN 9 faceoffs in Las Vegas

LAS VEGAS – With all fighters masked up, the faceoffs for UFC on ESPN 9 went down Friday in Las Vegas.

The UFC must follow strict protocols in conjunction with the Nevada Athletic Commission in order to have its next two events at the UFC Apex in Las Vegas. Masks are among the requirements.

That made Friday’s UFC on ESPN 9 weigh-ins a unique situation that we saw play out in similar fashion earlier this month in Jacksonville, Fla. But the Nevada rules are more strict, meaning unlike Florida, everyone was masked up.

Check out the video highlights from the faceoffs in the video above.

UFC on ESPN 9 takes place Saturday at the UFC Apex in Las Vegas. The event airs on ESPN and streams on ESPN+.
