Diego Sanchez seems to be thinking about going from a small welterweight to a big lightweight. Check out the following quote from his post-fight press conference:

"I feel that he beat me fair and square. I was close, but close isn’t close enough. All fighters go through losses, I’m just going to have to come back stronger. I’m contemplating in my mind if I’m going to drop to (1)55 or not, because I’m a smaller welterweight. I could do more powerlifting and put some more weight on or I could lose some weight."
