The NHL's future participation in the Olympics is in doubt.

Sources have confirmed to ESPN.com that the NHL, NHL Players Association and International Ice Hockey Federation met last week, at which point the IIHF updated all parties with the news that the International Olympic Committee is balking at reimbursing some of the expenses that were paid for in the past for the league and players.

The IOC has helped cover expenses such as insurance for players and travel costs ever since NHL participation commenced in 1998 at Nagano, Japan.

The news was first reported by Inside The Games on Saturday.
