Bill Peters has resigned as the Calgary Flames coach following an accusation he racially abused one of his former players a decade ago.
Earlier this week Nigerian-born Akim Aliu, who previously played for the Flames in the NHL, claimed Peters "dropped the N bomb several times towards me" when he was a minor league player "because he didn't like my choice of music".
The NHL released a statement calling the alleged comments "repugnant and unacceptable" and the Flames launched an investigation.
On Wednesday, TSN published a letter from Peters to Flames general manager Brad Treliving in which the coach apologised for "offensive language I used in a professional setting a decade ago".
In the letter, he also wrote: "Although it was an isolated and immediately regrettable incident, I take responsibility for what I said. The statement was made in a moment of frustration and does not reflect my personal values."
Aliu later called that letter "misleading, insincere and concerning".
Treliving conducted a press conference on Friday in which he revealed Peters, Calgary's coach since April 2018, had vacated his post.
"This morning I received a letter of resignation from Bill Peters, which I accepted," Treliving said.
"Effective immediately, Bill Peters is no longer a member of the Calgary Flames organisation."
