Well, MMA-ish techniques.
Here's an interesting sparring video between former Super-Bantamweight Champion, Daniel Ponce De Leon (41-4) and undefeated young prospect, Kevin Hoskins (4-0), as pointed to us by our friends at Bad Left Hook.
Things start out as a simple sparring session, until things go bad at around the 30-second mark of the clip. It could just be the 30-second warning, but De Leon appears to have thrown a punch after the bell, and then things started to escalate from there.
Tempers flared, and the boxing session suddenly became more like an ugly brawl from amateur MMA match.
Watch the video below where both fighters employ techniques such as an impressive looking Judo trip takedown, a couple of Badr Hari-esque stomp attempts, and also a few sucker punches and kicks as the coaches were trying to restrain the fighters.
As always, for the best coverage in all things boxing, head over to Bad Left Hook.
