The "Polish Experiment" has come to an end, with troubling results.
"I'm no longer fighting. I will never have another mixed martial arts fight ever again. My last fight in the UFC was December of 2011, and it was my first time ever getting literally knocked out cold. My brain didn't wake up for probably about 40 minutes after the fight. My first little training session [after that], I sparred with this little 155-pounder, and he hit me in the face, in the jaw, once. My brain literally said: 'No more.' I'm forgetting things. I'm forgetting my words. I'm mixing things up from time to time. Even counting backwards from like 20 down to 10 was tough. I knew right away then that it was time for me to move on and do something else. It's not getting worse, but it's not getting any better. But it's one of those things where I think it's the way it's gonna be for the rest of my life. It kinda sucks. You take all those little things for granted."
Krzysztof Soszynski won't be stepping into the cage ever again (unless it's here), after suffering significant memory loss following his last fight. The Ultimate Fighting Championship (UFC) light heavyweight hasn't competed since going stiff against Igor Pokrajac in late 2011. The knockout loss was the sixth of his career, which spanned a total of 38 professional mixed martial arts (MMA) fights, and caused what appears to be long-term damage. Probably something to consider when talking about the future of this fighter, and you can expect to hear more cases like this as the sport continues to evolve.
