MMA fighter lands controversial ONE-SECOND knockout, fans call head-kick 'dirty' and 'unsportsmanlike'

An MMA fighter delivered a sensational ONE-SECOND KNOCKOUT at Titan FC 83 - but the nature of the victory has divided fans online.

Luis Hernandez scored a huge win last Friday as he easily defeated Brian Topp at the Gulfstream Park in Hallandale Beach, Florida.

He landed a vicious head-kick right out of the gate to earn the win in the very first round, registering a one-second victory.

It was announced officially as one second at the event.

But MMA fans online are claiming Hernandez acted in an 'unsportsmanlike' way as he appeared to go for a glove touch before the start of their contest.

He seemed to offer his hand before connecting flush on Topp's chin with a devastating head-kick, which immediately slept his opponent.

Hernandez then landed a hammerfist for good measure before the referee jumped in to halt the bout.

He celebrated by hopping on top of the cage as he cut an animated figure. To his credit, he then checked on his stricken foe.

Hernandez's head-kick knockout split MMA fans on social media.

One Twitter user claimed: "Fake glove touch in there, and then the celebration makes it feel worse."

A second argued: "Protect yourself at all times."

A third added: "Nothing from body language said they were trying to touch gloves."

A fourth tweeted: "There’s no clearer definition of dirty."

Another commented: "Clean but unsportsmanlike as f**k."

Hernandez improved to 3-0 in his professional career, with three stoppage victories.

As for Topp, he fell to 1-5 with the crushing defeat. Four of his five losses have been in the first round.
