The NHL has given the players' association one more chance to deny claims it's threatening to decertify agents that represent replacement players.
In a letter obtained by the Associated Press, NHL Vice President Bill Daly asked the union to provide written confirmation by Friday that it has no intention of punishing agents. Barring a response, Daly said the NHL is prepared to file a complaint with the National Labor Relations Board.
This is the second time in a week the league has asked the union to disavow reported threats it has made to punish player agents.
The NHLPA's initial response came in a letter -- also obtained by the AP -- submitted by union lawyer Ian Pulver on Wednesday. In a two-paragraph statement, Pulver wrote the NHLPA had no intention at this time to change the agent-certification rules.
Daly, in his letter Thursday addressed to Pulver, called that response "insufficient."
