The National Hockey League Players' Association is voting on ratification of the Collective Bargaining Agreement with the National Hockey League.
The Union said on its website voting would start at 8 p.m. ET Thursday and continue for 36 hours, through Saturday at 8 a.m.
Secret ballots are cast electronically and the results will be announced Saturday morning after the voting window closes.
It is anticipated that if the CBA is ratified by the players, teams could open training camps on Sunday, with the regular season reportedly to begin on Jan. 19.
The NHL Board of Governors voted unanimously Wednesday to ratify the new 10-year CBA.
Commissioner Gary Bettman said the 2012-13 regular-season schedule would be released "instantaneously" after the players' ratify the CBA.
