Taking Steven Vertovec's concept of Superdiversity as a starting point, this special issue examines the dynamic interaction of diversity variables in the field of sport and migration issues. The articles published this Speical Issue span from studies on sports labor migration ( sports as migration) to consideration of the role sport plays in the everyday lives of disparate groups of migrants ( sport in migration). Considering the contemporary diversification of migration, we argue that it is more relevant than ever to expand the empirical focus of research in sports and migration issues, but also the breadth of theoretical and methodological approaches utilized. To this end, we illustrate the value of postcolonial theory and intersectionality as theoretical frameworks that can focus on multiple axes of differentiation along with structuring conditions that impact sports and migration issues. Further, we call for researchers in the field to consider the value of methodologies that are novel to their work such as participatory action research and approaches that avoid methodological nationalism.
