...by far, one of the roughest sports I’ve seen is not Hockey, Rugby, or even Aussie Rules FB, it;s Hurling.
...basically it’s kind of like hockey but played on a grass pitch with sticks (hurleys) and a small hard ball (sliotar). Use of the stick against an opposing player, while discouraged by rules, is still rather commonplace as it is in ice hockey. Mind you, the players including, the goaltender, wear no protective pads as they do in Hockey.
The ball can be propelled fast, exceeding 90 mph. “Tackling” involves use of the body (though shoulder “checking” is forbidden) or hurley.which includes two handed jabs or strikes.
The compulsory use of helmets with faceguards (in this sport which predates recorded Irish history) was only adopted two years ago.
