CHICAGO (AP) — A U.S judge will soon get his first chance to scrutinize a reworked deal in a class-action, head-injury lawsuit against the NCAA.

A Friday hearing in Chicago follows Judge John Lee’s December rejection of the first proposed settlement.

The second isn’t dramatically different.

It also requires the NCAA to create a $70 million medical fund to test current and former athletes in contact and noncontact sports for brain trauma. And like the first, it would toughen return-to-play rules after a concussion.

Lee complained the first agreement was murky in places, and the new settlement seeks to provide clarity. That includes new evidence to address Lee’s concern that the $70 million for testing won’t be enough.

He may take several weeks before giving a thumbs-up or down to the new proposal.
