The mediators and NHL Players' Association executive director Donald Fehr were back at the table Thursday but, unlike Wednesday, NHL commissioner Gary Bettman and deputy commissioner Bill Daly did not participate.
"There has been contact between the parties today," NHLPA special counsel Steve Fehr, who said he spoke with lead NHL counsel Bob Batterman, said.
"I think we're done with contact for tonight, expect there will be contact tomorrow but I am not sure if it will be by telephone or in person."
Bettman has said he cannot see the NHL, which normally runs an 82-game regular season, playing less than a 48-game campaign.
But with 42.8 per cent of the season already cancelled, time is quickly running out.
The two sides appear to have inched closer on the main sticking point of how to divide $3.3 billion in revenue.
The league is seeking an immediate 50-50 split while players, who will see their share chopped from 57 per cent, want the cuts brought in gradually with a "make whole" provision in place to cover money that would be lost on current contracts.
Several other contentious items remain on the table, including the length of a new collective bargaining agreement and contract limits to drug testing and continued participate in the Winter Olympics.
