Former two-weight champion, Conor McGregor was the first to weigh-in on tonight’s UFC Vegas 101 headliner between Mackenzie Dern and Amanda Ribas, congratulating the former on her redemption against the Brazilian with a late third round armbar submission win in the night’s main event.
Dern, who first faced off with Ribas back in 2019 in a trip to Florida, dropped her first-ever professional mixed martial arts loss to the Minas Gerais native — seeing her perfect run of seven consecutive wins halted as a result in a unanimous decision loss.

And tonight, avenging her loss five years after the fact, Arizona-born Jiu-Jitsu queen, Mackenzie Dern turned in her eighth career submission win against Brazilian foe, Ribas — wrapping up a late armbar submission win just less than 10-seconds remaining in the frame.
