Here's their announcement in Facebook:
https://www.facebook.com/prorugby/posts/976181645783692We are happy to announce Ohio as our fourth team for PRO Rugby's upcoming inaugural season. Ohio will play its matches in the city of Obetz. We thank the City of Obetz for their help in making a team in Ohio possible. We are excited about building the stadium experience and hopefully this model will allow for expansion in other areas of the country that do not have existing venues that fit the rugby match criteria.
