The Tri-City Americans will finish their playoff run without defenseman Drydn Dow, whose right arm was broken when he was checked from behind by Everett's Manraj Hayer at 2:34 of the first period of Game 2 on Saturday night.
Dow has a cast from his shoulder to his hand.
Hayer was assessed a double minor for checking from behind at the time of the hit, but the Western Hockey League added onto Hayer's penalty Monday.
WHL disciplinarian Rick Doerksen suspended Hayer for an undetermined amount of time.
"The league addressed it appropriately," Tri-City general manager Bob Tory said. "Drydn is one of our top four defenseman. This is a big, big blow caused by a reckless play."
On top of Hayer's suspension, the WHL also suspended Everett forward Ryan Harrison one game for an open-ice hit on Tri-City forward Jesse Mychan at 9:44 of the first period Saturday.
In addition, the Silvertips were fined $500 by the WHL for violation of the WHL social media and networking policy.
"Everett sent out a tweet prior to when they should have, and it was derogatory in nature," Doerksen said. "We aren't going to catch everything, but if you are caught doing it, then you will be punished."
As with all major penalties, the WHL took a look at Cody Fowlie's hit on Tri-City's Patrick Holland at 4:20 of the third period. Fowlie checked Holland into an open gate in front of the Silvertips bench and was given a major for checking from behind and a game misconduct. No additional penalty was handed out by Doerksen.
