Retired players accuse the NFL of conspiring to hide evidence that concussions could lead to dementia and brain disease in the latest lawsuit filed over the issue.

The fraud and negligence lawsuit filed Wednesday in Philadelphia accuses the league of publishing nonscientific papers written by biased members of its medical committee. The plaintiffs include former Philadelphia Eagles Ron Solt and Rich Miano.

At least eight similar lawsuits have been filed across the country. The players seek compensation for mild to severe mental disabilities or funds for medical monitoring.

More than 100 players have signed on to the various lawsuits.

The NFL vows to vigorously defend the claims, saying player safety has always been a priority.

The league will ask federal judges next week to consolidate the cases in Philadelphia.
