The life of a referee is never easy. Managers, players and fans dislike them in equal measures, howling with derision after every blow of their whistle.

Howard Webb, Mark Clattenburg and Cuneyt Cakir have all received their fair share of abuse in recent weeks and months - but they could never in a million years expect to have something like this happen to them.

An unnamed ref in Brazil's Paulista A3 league innocently signalled that there was to be four minutes of extra time in Independente de Limeira’s 1-0 defeat to Marilia on Saturday.

Seems fair enough doesn't it? Well, not if you're Johnny dos Santos, who took exception to the ruling, and decided to take the law into his own hands.

The 25-year-old jogged up to the referee innocuously enough, only to launch a vicious karate-kick at his throat, leaving the man in black flat-out on the deck and in serious pain.

You won't be surprised to hear that Dos Santos received a red card for actions and his side still lost. Check out the video above.
