CHICAGO (AP) — A federal judge has rejected a proposed $75 million head injury settlement with the NCAA as too broad.

U.S. District Judge John Lee in Chicago issued a 21-page ruling Wednesday denying preliminary approval. He did say the deal could be altered to address his concerns, which include the scope of the proposal. At an October hearing, he raised similar concerns, saying, “The settlement, as it’s constituted, includes every athlete for all time.”

Under the settlement, NCAA would toughen return-to-play rules for players with concussions. It would also create a $70 million fund to test current and former athletes for brain trauma, and set aside $5 million for research.
