They are in boxing gloves, but dang they are slugging each other hard in the face.

This one armed boxer knocks out his opponent lol I would hate to get knocked out by a one armed person.

3+mins of amazing knockouts

Floyd Mayweather 2 Minute KO Over Cooper

Tyson is 20 years old here, see how fast and strong he is. Trevor Berbick has actually won Muhammed Ali back in the days.
