Thinking about this again i don't think Jeff Lacy has it in him to quit he is a proud man and comes accross as the type of guy that doesn't quit in anything he does i honestly can't seem him retiring i just think he is really frustrated that he knows he can perform better and im sure his training is all well and good but he just can't perform on the night i thought he looked fine against Vitali Tsypko until his shoulder gave out i would say that was his last good performance maybe the injury is still bothering him.
