A source with firsthand knowledge of the regulations that would be in place for an anticipated 2017 NHL expansion draft told The Post that, contrary to initial information reported on Sunday, teams only would be compelled to protect players with no-move clauses (and contracts) that extend through at least the 2017-18 season.

That means that players whose no-move clauses (or contracts) that expire at the end of 2016-17 would not have to be protected.

That class of players would include Rangers defenseman Dan Girardi, whose no-move clause will become a modified no-trade clause as of July 1, 2017; Lightning goalie Ben Bishop, who is eligible to become an unrestricted free agent on that date; and Flames defenseman Dennis Wideman, whose no-move and contract both expire after next season.

The NHL, whose executive committee met on Tuesday in New York, is expected to expand to Las Vegas for the 2017-18 season. The Board of Governors is expected to vote when it convenes on June 22 — in Las Vegas.
