Alex Pereira, the UFC light heavyweight champion (93 kg), a Brazilian mixed martial arts master, trained with American media magnate Mark Zuckerberg.
Idman.Biz reports that Pereira tested Zuckerberg both on his feet and on the ground.
Zuckerberg even knocked Pereira down. "Are you okay?" the businessman asked after Alex got up.
In his last fight, on October 5, at "UFC 320" in Las Vegas, USA, Pereira regained his belt by defeating Russian Magomed Ankalaev by technical knockout in the main fight.
