This list of manly sports include a couple I've never heard of, including Calcio Fiorentino.
This Italian sport originated in 16th century Florence. Called Bareknuckle Football, it’s a manlier version of, well, everything. Punching, head-butting, and choking are all legal. In 50 minutes each team tries to score as many points (cacce) as possible. In simpler terms this means that whichever team beats up the other more effectively will win. The closest thing we have to modern day gladiatorial combat. Seriously, they used to release prisoners to perform. Manly.
Most of the sports listed are violent or injury-inducing, but not all. Link -via the Presurfer
