A day after collective bargaining agreement negotiations broke down again, the NHL announced Friday the cancellation of its 2012-13 regular-season schedule through Nov. 1 because of the owners' lockout.

That left open the possibility, however, of playing a full, 82-game regular season that opens on Nov. 2, which was the stated goal of the CBA proposal the NHL submitted to the players on Tuesday.

The NHL had previously canceled its schedule through Oct. 24, so only one additional week of games was scrapped and there is still the possibility of rescheduling them. The league and its players would have to reach an agreement by Oct. 25 to fit in a one-week training camp and start the regular season on Nov. 2.

If an agreement is not reached by Oct. 25, the NHL will likely announce the cancellation of a larger chunk of the schedule. After the NHL quickly rejected three proposals submitted by the players during Thursday's meeting in Toronto, the next round of negotiations have yet to be scheduled.

The NHL has canceled a total of 135 games for the first three weeks of the schedule.
