WASHINGTON (AP) — Ten former National Hockey League players are claiming in a class-action lawsuit that the league hasn't done enough to protect players from concussions.


The lawsuit, filed Monday in federal court in Washington, seeks damages to be determined at trial. The players are also seeking court-approved medical monitoring for their brain trauma and/or injuries, which they blame on their NHL careers.


The suit comes just three months after the National Football League agreed to pay $765 million to settle lawsuits from thousands of former players who developed dementia or other concussion-related health problems.


The ex-hockey players claim that the NHL purposely concealed the risks of brain injuries faced by players, exposing them to unnecessary dangers.


The NHL didn't immediately respond to a request for comment.
