More than three years after the NFL and a class of thousands of former players agreed on terms of the settlement of the concussion class action, the settlement still won’t be finalized.

Contrary to a report in the New York Post that the remaining players objecting to the deal had failed to file petitions for appeal with the U.S. Supreme Court by Monday’s deadline, at least one petition was filed and multiple others may still be pursued.

The Estate of Cookie Gilchrist, who played six years in the AFL prior to the merge with the NFL, filed a petition that attacks certain aspects of the science that underpins the settlement.

Also, two separate groups of players objecting to the settlement, led by Raymond Armstrong and Kelvin Kight, received extensions of the deadline for filing petitions for appeal, through September 19.

It’s highly unlikely that the U.S. Supreme Court will accept the cases for review. Which means that the three-year delay in transforming the settlement into payments to eligible former players will continue, indefinitely.
