David Tua and Andrew Golota sparring incident; low blows from both fighters!

Just did some research on relations between David Tua and Andrew Golota, as both of them were fighters on the 'Young Heavyweights' card, and an excerpt from an ESPN article featuring words from Ronnie Shields, One of David Tua's former trainers, includes a interesting incident:

His ability to walk through his opponent's shots abetted that tendency. It also led to some interesting sparring sessions in the early days, when both Tua and Golota were promoted by Main Events.

"We were training down in Vero Beach, Florida and we let David and Andrew spar together," Shields remembered. "I was training David and Roger Bloodworth was training Andrew. It was like a real fight, back and forth. And then Andrew started hitting David low. David went back at him, hitting Andrew low.

"They just went back and forth hitting each other low. It was crazy. We had to jump in there and stop them. Andrew was a big, strong guy who could really hit. I think it angered him that he couldn't hurt David even though David was so much smaller than he was. That's why he started hitting him low."
