Post–playing career Playing as an enforcer throughout his hockey career, Walker required 17 surgeries to repair injuries. He criticized the NHL Alumni organization, which he claimed did not support retired players enough financially. As a result, he created an organization called Dignity after Hockey to raise awareness and funds to provide health care to retired players. In 2017, he added his name to a class-action lawsuit against the NHL alleging neglect of support for players suffering injuries and financial strain once retired. == Death ==
