The National Hockey League alleges in a new court filing that it is not to blame for any of the injuries or health problems suffered by former NHL player Steve Montador, who was posthumously diagnosed with chronic traumatic encephalopathy (CTE) after his death in 2015.

Montador was 35 when he died on Feb. 15, 2015. Three months after his death, researchers with the Canadian Sports Concussion Project at Toronto’s Krembil Neuroscience Centre disclosed the former defenceman had suffered from CTE.

Montador’s family sued the NHL in December 2015, alleging the league has promoted violence and profited off of it while not adequately advising players of the risks of repeated long-term brain injuries.

The Montador family’s lawsuit against the NHL was put on hold for four years while the NHL fought a proposed class-action lawsuit filed by more than 100 former NHL players. Now that there is a settlement in that case – which bars nearly 300 former players and their families of pursuing legal action in the future in exchange for a $22,000 (U.S.) per player settlement –Montador’s case is moving forward.
