A group of retired NFL players who objected the $1 billion concussion settlement decided to drop their appeal.
The players had until Monday to file an appeal to the Supreme Court.
In July 2014, a federal judge granted preliminary approval to the National Football League's $765 million settlement, after 4,500 ex-players filed the lawsuit against the league claiming the NFL hid known concussion risks, leading to high rates of dementia, depression and even suicides.
That amount was upped to $1 billion with the settlement covering more than 20,000 retired players for the next 65 years. A federal appeals court in June unanimously upheld the deal, with the NFL admitting no fault.
