KANSAS CITY, Mo. -- Five former Chiefs players who were on the team between 1987 and 1993 filed a lawsuit Tuesday claiming the team hid and even lied about the risks of head injuries during that period, a time when there was no collective bargaining agreement in place in the NFL.
The lawsuit, filed in Jackson County Circuit Court on behalf of former players Leonard Griffin, Chris Martin, Joe Phillips, Alexander Louis Cooper and Kevin Porter -- all of whom played on defense -- seeks undisclosed financial damages. All five players have opted out of a multimillion-dollar settlement announced this summer that would compensate former players for their head injuries.
The Kansas City plaintiffs claim to be suffering from post-concussion syndrome and latent brain disease because of multiple concussions they sustained while playing for the Chiefs. They all also claim to be suffering from chronic traumatic encephalopathy, which can only be definitively diagnosed by examining the brain after death.
Chiefs spokesman Ted Crews and NFL spokesman Greg Aiello both declined to comment on the suit.
The lawsuit says the Chiefs ignored decades of research indicating that concussions cause long-term brain damage, instead referring to the injuries as "getting your bell rung'' or a "ding.'' It accuses the team of lying to players in saying concussions were not serious injuries.
In recent years, several former NFL players and other athletes who suffered concussions have been diagnosed after their deaths with CTE, including Junior Seau and Ray Easterling, who both committed suicide.
In August, the NFL agreed to pay approximately $765 million to settle lawsuits filed by more than 4,500 former players who developed dementia or other concussion-related health problems they say were caused by playing football. The settlement, subject to approval by a federal judge in Philadelphia, would apply to all past NFL players and spouses of those who are deceased.
Plaintiffs' attorneys say individual payouts would be capped at $5 million for those with Alzheimer's disease; $4 million for those diagnosed after their deaths with CTE; and $3 million for players with dementia.
About 19,000 retired players would be eligible to seek awards or medical testing, but current players are not part of the deal. The settlement does not include an admission from the NFL that it hid information from players about head injuries.
At the time, the settlement announcement appeared to remove a major legal and financial threat hanging over the NFL. But if too many former players opt out, the deal could fall apart.
