Nine former players have sued the NHL over concussions, saying the league subjects its players to ''devastating and long-term'' health consequences by failing to warn players of the risks and consequences of head trauma.

Among the players are former All-Star defenseman Brad Maxwell and Jack Carlson, whose brothers starred in the film ''Slapshot.''

The lawsuit in Manhattan federal court was filed late Wednesday, several months after a similar lawsuit was filed by 10 former NHL players in Washington. Both lawsuits seek unspecified damages, along with a medical monitoring program to care for former and current NHL players.

A message for comment from an NHL spokesman was not immediately returned.

The lawsuits were filed just months after the NFL agreed to pay $765 million to settle lawsuits from thousands of former players who developed dementia or other concussion-related health problems. That settlement is awaiting a judge's approval.
