Maryland

With the signature of Governor Nathan Deal, Georgia became the 45th state to enact a so-called Zackery Lystedt concussion safety law since May 2009.  Of the remaining five 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, a bill is awaiting the signature of the governor in one (West Virginia), and legislation is pending in another (South Carolina), leaving only one (Mississippi) with no law or bill pending.
