(CP) - Chicago Blackhawks defenceman Adrian Aucoin may be headed West - if he wants to.

The Blackhawks have agreed to trade Aucoin to the Calgary Flames and are waiting to see if the 33-year-old will waive his no-trade clause, a source told the Canadian Press on Thursday. Aucoin has a prior relationship with new Flames head coach Mike Keenan, having played under him with the Vancouver Canucks during the 1998-99 campaign. Aucoin finished with a career-high 23 goals that season.

Aucoin, 33, had four goals, 12 assists and a minus-22 rating in 59 games for the Blackhawks last season. The six-foot-two, 215-pounder missed 23 games with a groin injury.

Aucoin has two years left on a deal that will pay him US$4 million per season. An all-star in 2003-04, he has 88 goals and 179 assists in 694 career games with Vancouver, Tampa Bay, the New York Islanders and Chicago.

Sources tell TSN that Chicago defenceman Adrian Aucoin has agreed to waive his no trade clause to permit a deal that would send him to the Calgary Flames.

In exchange, the Flames will send defenseman Andrei Zyuzin to the Blackhawks.

Sources say the paperwork and formal approval of the transaction will be completed on Friday. The deal, therefore, cannot be deemed official until then. But Aucoin is prepared, the sources said, to be a Flame and the Blackhawks and Flames have agreed on the terms.

The Flames were in the market for a defenceman and zeroed in on Aucoin, who has a history with new Calgary coach Mike Keenan. In 1998-99, Aucoin scored 18 of his 23 goals on the powerplay for Keenan's Vancouver Canucks.

At $4 million a season, Aucoin carries a price tag the Blackhawks were looking to shed.

Zyuzin, who was signed by Calgary as a free agent last July, is scheduled to make $1.45-million next season.

Last season, Aucoin had trouble with a groin injury and played only 59 games for the Blackhawks. He scored four goals and 12 assists for 16 points. he was a -22 on the season. The year before that, Aucoin only played 33 games, scoring one goal and five assists.

In 694 NHL games, Aucoin has 88 goals and 179 assists for 267 points and a +15 rating.

In 49 games last season, Zyuzin had 1 goal and 6 points. He missed 14 of 16 games in December and January with a knee and groin injury and was a healthy scratch for 12 games late in the season.
