With the signature of Governor Earl Ray Tomblin, West Virginia became the 46th state to enact a so-called Zackery Lystedt concussion safety law since May 2009.  Of the remaining four states, Wyoming has enacted a weak concussion safety law, the high school athletic association in Arkansas has rules that mirror the concussion laws of other states, legislation is pending in another (South Carolina), leaving only one (Mississippi) with no law or bill pending.
