Halocho #712 - Is boxing a Kosher sport?

It is forbidden to hit a fellow Jew.

One who hits another Jew has transgressed a Torah prohibition.

Even one who simply lifts his hand with the intent to hit is called "wicked" as we learned in last week's Parsha (Shmot); "[Moshe] said to the wicked one: Why are you going to hit your friend?" - even before he hit, he was referred to as the wicked one.

Hitting back in self-defense is permitted, if there are no other options.
