The NHL and the players' association had their longest negotiating session in nine months, and the league presented six possible concepts for a new economic system.
Little progress was made on a new deal, but the representatives met for four hours in the league's Manhattan office to try to come up with a plan that would prevent a lockout next season. It was the fourth meeting since negotiations began in October.
Bill Daly, the NHL's chief legal officer, said talks were substantive and that there was a detailed discussion on at least some of the proposed ideas. He added that NHLPA negotiators requested more information that the league will provide before the parties meet again Aug. 4 in Toronto.
