Mike Ribeiro’s hockey career “is at an end” after he suffered a relapse, his agent and longtime friend Bob Perno has told Montreal media outlets.

The concern, however, shouldn’t be with his playing career but with his own personal health and well-being. In revealing interviews with La Presse and TSN 690 on Thursday, Perno went into detail about the depths of Ribeiro’s struggle with substance abuse, saying that he has been unable to contact his client.

“All I know, is that Mike hasn’t laced up the skates once since the end of the season,” Perno told La Presse (his quotes have been translated from French into English). “He doesn’t train anymore and he doesn’t go out on the ice anymore. He’s going to retire. There’s not one NHL team or a team in Europe that has reached out to me to ask about him. The way his career is going to end is really disappointing.

“No one knows what he’s up to these days. The problem, is that Mike doesn’t believe he’s sick. In his head, everything is fine. He left the rehab program offered by the NHL last winter. We’re really worried, but we can’t do anything. Every time my phone rings, I hope it’s him calling me.”

Ribeiro, now 37 years old, entered the NHL/NHLPA substance abuse and behavioral health program at the end of the 2013-14 season, according to Puck Daddy. His agent told TSN 690 that Ribeiro was clean for about two years, but that he suffered a relapse before Christmas.
