Matt Borne - Family of Doink The Clown sues WWE for brain injuries

Family of Doink The Clown sues WWE for brain injuries is the headline of an article from www.Wrestling-online.com today.  It seems as though many wrestlers families, and even Billy Jack Haynes, are suing the WWE for these injuries.  I wonder about the outcome of these cases.  Even though we didn't know the extent of concussions in the 80's, it doesn't mean people didn't realize that hitting your head could hurt your brain.  I just don't see how anyone could win at these cases.
