Nyquist had waived his right to an in-person hearing and instead had a phone hearing Wednesday afternoon with the league office.
The incident took place Sunday, when Nyquist appeared agitated by Spurgeon's attempt to cross-check him in the back along the boards. He retaliated by shoving his stick blade in Spurgeon's face.
Nyquist was assessed a four-minute double minor penalty for his actions but was not ejected. Spurgeon left the game briefly but returned.
The suspension will cost Nyquist $158,333.
Nyquist, 27, doesn't have a prior record of discipline with the Department of Player Safety. After the game, Nyquist said his high stick was not intentional.
The 27-year-old Swede has seven goals and 22 assists in 56 games this season.
