Ice hockey enforcers are letting their fists fly inside the rink in a brutal no-holds-barred combat sports event called Ice Wars in Canada.

The bizarre competition sees men from across the country - often of varying shapes and sizes - do battle like Rock 'Em Sock 'Em Robots.

Ice Wars, or to give it its full name 'Ice Wars International', combines boxing, ice hockey and mixed martial arts.

According to the rules, headbutting, kicking and biting is strictly prohibited, while contestants also must not pull their opponent's hair, knee them, or trip them up.

They are also not allowed to hold each other's gloves which it's worth pointing out are little more than hand wraps.

Helmets and gloves must also stay on at all times during a fight.

The organisation was created in January and last weekend hosted its first professional show in Edmonton, Alberta.

Broadcast partner FITE TV, who own the streaming rights, shared footage taken during its inaugural pay-per-view event.

And it shows two men bashing the living daylights out of each other in front of a raucous crowd.

The video has been retweeted more than 100 times, liked by almost 500 and viewed over 100,000 times.

But A.J. Galante, the league's president and founder, admits it's not for everyone.

Galanta told Yahoo! Sports: "It's a play on something that has been part of hockey lore and tradition — but it's not hockey.

"It's not going to be for everyone, but I believe there is a huge market for it, and I believe we're going to do something special.

“We’re taking as much precaution as possible.

“You’re conducting a combat sport, you want exciting fights, you want entertainment, you want fun… but from the forefront… for everyone involved, player safety has been the number one thing.

"We’re putting player safety first, I think we’re safer than the current NHL.

“This isn’t cock fighting, we actually put a lot of thought in, and looked at a lot of data.

"Of course, there’s always going to be that inherent danger, this isn’t ballet.

“These guys know what they’re getting into, but trust me, no one is hoping anyone gets hurt, but it’s, unfortunately, the nature of a combat sport.”
