The U.S. Third Circuit court of appeals on Monday upheld the settlement the NFL reached with retired players in 2013 to resolve a concussion-related lawsuit. The settlement, which originally totaled $765 million, was revised such that it was expected to reach $900-plus million.

The revised settlement was provisionally approved in April 2015 by a Judge Anita Brody of the U.S. District Court in Philadelphia, who called the settlement "fair, reasonable and adequate." Objectors to the settlement appealed it to the Third Circuit in November 2015.

According to a report, the settlement calls for former players diagnosed with certain neurological disorders to receive payments of up to $5 million each. In announcing the decision to uphold the settlement, the Court on Monday said that though it was "not perfect, it is fair."

As stated by legal analyst Andrew Brandt, it is important to note that the NFL admitted no liability in its settlement with retired players. The lawsuit was brought on behalf of more than 5,000 retired players. It could eventually cover more than 21,000 former players, according to the court.
