In a letter sent to general manager Brad Treliving, Calgary Flames coach Bill Peters addressed accusations of making racist comments toward a player in 2009.
In the statement obtained by TSN Peters admits to using "offensive language" in a professional setting as the former Rockford IceHogs head coach.
"The statement was made in a moment of frustration and does not reflect my personal values," Peters wrote. "After the incident I was rightfully challenged about my use of language, and I immediately returned to the dressing room to apologize to the team. I have regretted the incident since it happened, and I now also apologize to anyone negatively affected by my words.
