A Canadian Hockey League statement said a member of the Rockets' organization made "negative comments" about the referees to members of the CHL hockey operations department after a 4-3 loss to the host Quebec Remparts on Friday night.
They did not specify which member of the team's brass made the comments.
Kelowna had 44 penalty minutes on 10 infractions. The Remparts were on the power play five times, but didn't score.
It was the referees' decision to hand 10-minute misconducts to star Leon Draisaitl and Quebec centre Marc-Olivier Roy for a scuffle at the end of the second period that seemed to anger the Rockets. It took away Kelowna's top scoring threat for an extended period at a time they were trying to get back a game they trailed 2-1.
Neither coach Dan Lambert nor Draisaitl criticized the referees in post-game media interviews. They spoke of adapting to a different approach to officiating than they are used to in the Western Hockey League and the need to be more disciplined in future games.
The Rockets play their second game of the four-team tournament Monday against the Rimouski Oceanic.
