Oilers fans are furious after huge officiating mistake may have cost them the series

For those who missed the action, Mattias Ekholm suffered a high-stick to the face during the closing moments of the third period.

Here's a video of the incident that would make even a die-hard Golden Knights fan raise an eyebrow:

This leaves no room for doubt that a penalty flag should have been raised on that play.

In the Oilers' exit interviews today, Ekholm showed up visibly marked by the impact.

It's no secret that the Oilers' power play has been powerful all season. Every time their special teams skated out, fans anticipated a goal.

In the last game, they were only trailing by two goals. With a four-minute power play, the outcome of the game could have been different.

Do you think the officiating mistake cost the Oilers their victory?
