UFC Fight Night has gotten off to an exciting start with this brutal, one-punch KO

He dominated from the beginning.

Exciting fights don't need to be long. Today's UFC Fight Night 107 bout in London is a good example.

It took just 30 seconds for Marc Diakiese to crush Teemu Packalen in a spectacular way.

Diakiese (12-0 MMA, 3-0 UFC) dominated from the beginning, and was on the attack from the start. And then, he threw one punch that put Pacalen (8-2 MMA, 1-2 UFC) to sleep.

Brutal.
