TORONTO (AP) _ The Toronto Maple Leafs traded restricted free agent Alexander Karpovtsev to the Chicago Blackhawks on Monday in exchange for defenseman Bryan McCabe.

Chicago also received a fourth-round draft pick.

Karpovtsev missed training camp after contract talks with the Leafs reached an impasse during the summer. The defenseman had been working out with Moscow Dynamo, but played his last game there last Thursday. If he played any games in the Russian League beyond Wednesday, he would have had to be put on waivers before he could return to the NHL.

``We spent all of training camp trying to improve our defense without having to trade a defenseman that was already on our team,'' Chicago general manager Mike Smith said Monday. ``We decided to acquire Alexander Karpovtsev and in order to do that we had to give up Bryan McCabe.''

Smith was the Leafs GM when Toronto acquired Karpovtsev, originally drafted by Quebec in 1990, from the New York Rangers in 1998

Karpovtsev had three goals and 14 assists in 69 games last season. He also had three assists in 11 playoff games. Karpovtsev has 27 goals and 114 assists with 317 penalty minutes in 405 career games.

McCabe had six goals and 19 assists in 79 games last season. He has 32 goals and 89 assists and 394 games.
