Ryan O'Byrne couldn't crack Montreal's lineup after the first week of the season.

The Montreal Canadiens sent idle veteran Ryan O'Byrne to the Colorado Avalanche on Thursday in exchange for Quebec teenager Michael Bournival.

O'Byrne, 26, was a reliable defender in the first two rounds of the playoffs as Montreal was hit by injuries on the blue-line, but he fell out of coach Jacques Martin's rotation early on this season.

The six-foot-six O'Byrne has played just three games this season for the Canadiens and none since Oct. 13. The Habs won six of the next seven, and O'Byrne couldn't get back in even before star Andrei Markov returned Oct. 30 from an injury.

He spent all 128 career regular season NHL games with Montreal, with two goals, 12 assists and 181 penalty minutes. 

Bournival, 18, is in his third season with Shawinigan, his hometown team. The forward has 10 goals and 14 assists in 17 games with the Cataractes so far this Quebec Major Junior Hockey League season.

The Avalanche selected Bournival in the third round of the June entry draft.
