A federal panel ruled that all concussion-related lawsuits brought by retired N.H.L. players would be consolidated into a single suit and heard by the United States District Court in St. Paul, Minn.
Former N.H.L. players have filed about half a dozen concussion-related suits across the United States, with more former players expected to file in the near future.
In issuing the consolidation order, the Judicial Panel on Multidistrict Litigation said it had chosen Minnesota in part because of its proximity to Canada, where several of the plaintiffs live.
