Arizona Coyotes defenseman Jarred Tinordi has been suspended for 20 games without pay for violating terms of the NHL's performance-enhancing substances program.
The NHL announced the suspension Wednesday.
Tinordi said in a statement released by the NHL Players' Association that he did not knowingly take a banned substance.
"I understand, however, that I am responsible for what enters my body as a professional athlete and I accept the suspension," he said. "I will work hard towards my return to the ice and will learn from this frustrating setback."
Tinordi was acquired by the Coyotes in January in a series of trades that sent enforcer John Scott to Montreal.
He has 17 penalty minutes in 10 games with the Canadiens and Coyotes this season.
