"Walkowiak and Watkins claim that Watkins also reported DeLorenzo's alleged behavior to the NHL HR Vice-President Patrice Distler and Katherine Watson, an NHL lawyer, in December 2019. Watkins alleged he told the NHL executives that there was video evidence of DeLorenzo's alleged racist statements."
Per reports, the two were worried that they may be fired for reporting the incidents. The league has since fired Di Lorenzo and Brace and has provided to the courts six recordings exemplifying the racist behaviour.
"The NHL fired Brace and DeLorenzo on Jan. 2, 2020. Walkowiak and Watkins were fired on Feb. 27, 2020, for allegedly being involved in a group text message thread of DeLorenzo's years earlier."
In a statement prepared by NHL lawyer Emily Chase-Sosnoff, the league maintained that the two were fired subsequently for making homophobic and racist remarks in a group-chat prior to the main investigation.
