NEW YORK - After 6 1/2 hours of negotiations, labor talks broke down Saturday, leaving the already canceled NHL season beyond saving.

Just three days after the season was called off because of the protracted lockout, the NHL and the union restarted talks in New York. Commissioner Gary Bettman and players' association executive director Bob Goodenow weren't in attendance, but Wayne Gretzky and Mario Lemieux, two of hockey's greatest starts, were there.

However, Gretzky, the managing partner of the Phoenix Coyotes, and Lemieux, the player-owner of the Pittsburgh Penguins, couldn't help the sides bridge the gap over the salary cap.

Last Wednesday, Bettman canceled the season, saying it was too late to play any semblance of a schedule.
