The Vegas Golden Knights placed forward Max Pacioretty on injured reserve Wednesday with an undisclosed injury, according to NHL.com's Danny Webster.

The designation is retroactive to Dec. 17 and means that Pacioretty will be out until at least next Monday. He will subsequently miss at least three games, including Saturday's contest that will see the Montreal Canadiens visit T-Mobile Arena.

Pacioretty will miss the opportunity to face his former team for the final time this season. Last month, he was held pointless in his return to Montreal, despite firing a season-high nine shots on goal.

The 30-year-old was forced from Monday's game against the Columbus Blue Jackets after appearing to suffer a lower-body injury on a play in the second period.

In 30 games this season, he has recorded 10 goals and 19 points.
