TORONTO (AP) - Toronto Maple Leafs who live outside the city will have to pay their own way to the NHL team's training camp this year.

The club confirmed Monday that it is under orders from league commissioner Gary Bettman not to pick up players' travel expenses.

''That's part of the negotiating posture,'' said assistant general manager Bill Watters, who normally makes travel arrangements for out-of-town players. ''But I think (the players) can handle it.''

Bettman last month threatened the players with $20-million worth of contract rollbacks in an effort to force their union back to the bargaining table. The last collective bargaining agreement between the league and its players expired Sept. 15, 1993.

The Leafs are to open training camp Sept. 4.
