I hope this isn't true, but we shall see. The funny thing is along with the seemingly reliable news of the elbow injury, I was over at sherdog (I really need to remove that site from my 'favorites!!) and saw a headline about GSP having a groin issue. It also states that he would let UFC know by Wednesday. In regards to who should replace him, Diego could possibly pull off fighting in a month, Leben wasn't off that long in between fights. I don't think it would be a good idea, but it would be better the Penn getting the shot. I just can't picture giving someone who lost his last fight. I realize he's a proven fighter, but he did lose his last fight. Hopefully none of this will matter and GSP will be able to fight, at 100%.
