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 don't think that the fight went on long enough or was decisively one sided enough for anyone to "want out" at that point. It was a legitimately hard shot to the junk and Spiritwolf was the only person with the ability to determine how much it actually hurt.
