Investigations are underway at Mount Si and Mount Vernon High Schools following the state playoff football game on Nov. 9. Each team’s football coaches have been reported for allegedly displaying unsportsmanlike behavior during Friday’s game.

The class 4A playoff game between the Mount Si Wildcats and the Mount Vernon Bulldogs was “a very close and intense competition,” according to a prepared joint statement from Snoqualmie Valley Superintendent Rob Manahan and Mount Si High School principal John Belcher.

Mount Si beat Mount Vernon 39-38. However, tensions rose several times throughout the game.

A live-streamed Youtube video of the game as well as a King 5 live video shows both football coaches, Nic Vasilchek of Mount Vernon and Charlie Kinnune of Mount Si, arguing about behavior on and off the field. Kinnune accused Vasilchek of letting his players stomp on the Mount Si logo at midfield.

Tensions rose again at halftime shortly after a disputed call on an extra point kick, prompting officials to call both teams back out for a second attempt. When the second kick was blocked, Vasilchek allegedly ran onto the field and waved his arms at the Mount Si fans in celebration.

A 22-year-old man from North Bend pushed another person in the crowd as the players were leaving the field. The male was led off by police and arrested for disorderly conduct. Alcohol was involved, according to a Snoqualmie Police spokesperson. No injuries have been reported at this time.

According to King 5 news, Kinnune approached a King 5 cameraperson and attempted to grab the camera, as he shouted for the cameraperson to show their press credentials. According to a Snoqualmie Valley School District representative, the King 5 cameraperson was not wearing any press credentials.

Manahan and Belcher said the school takes “full responsibility for our behavior,” in a prepared statement.

“There were some behaviors that were in our control, and some that were not — on the part of both teams. With the emotional nature and high intensity of the competition, admittedly, there were times when our team and coaching staff did not respond with the high character and sportsmanship that Mount Si High School has worked hard to instill,” Manahan and Belcher said in the release.

To ensure a similar incident does not occur in the future, director of athletics and activities for Mount Si Darren Brown said there will be a safety meeting at the upcoming Nov. 16 football game against Puyallup. That meeting will not be open to the public.

A Snoqualmie Valley School District representative also said future games held at Mount Si will require all press to have visible credentials, or check in with a school official upon entering school grounds.

Both schools are under investigation and no formal discipline or reprimanding of the coaches had been enforced as of this story. Neither coach could be reached for comment.
