UFC lightweight Danny Castillo  was having a bad day. Two months of training, it seemed, were down the train. In the past that would have likely meant a couple of cold beers to drown his sorrow. Now things are completely different. “I was just having a really bad day, and what makes me feel better is to go out and make someone else’s day,” Castillo told MMAjunkie.com (www.mmajunkie.com). Castillo (15-5 MMA, 5-2 UFC) had just been informed his planned UFC on FOX 8 opponent, Bobby Green (20-5 MMA, 1-0 UFC), had been forced to withdraw from the July 27 contest. With just two weeks before the bout, Castillo wasn’t certain if the UFC would be able to find a replacement opponent in time to keep him on the card.
