CHICAGO (AP) — There is a new proposed settlement in a head injury lawsuit against the NCAA brought by football players and other college athletes.

Notice of a new deal came in a filing in federal court in Chicago late Tuesday night.

It’s the second proposal in the case. U.S. District Judge John Lee rejected the initial settlement in December.

The core of the new agreement is the same as the one Lee rejected. The new one also would toughen return-to-play rules after a concussion and would create a $70 million fund to test current and former athletes in contact and non-contact sports for brain trauma.

The new proposal also seeks to address Lee’s criticism. That includes his concern there was a lack of clarity about how athletes normally designated as non-contact sports could benefit if they suffer concussions.
