I guess Davis learned his lesson about fighting guys with losing records. We all know nut shots hurt, but I've never been hit in the nuts to the point where I wasn't alright after 5 minutes of rest. The guy probably wanted out. A shame really because Spiritwolf is sort of a cool name and it seems wasted.
I have seen Spritwolf fight a couple of times and he didn't seem like the type to do that. I believe he had hurt Davis just prior to that as well. But like you it's only my opinion and the only person that can know for sure is Spiritwolf.
