The fine, announced Thursday by the NHL’s Department of Player Safety, is the maximum allowable under the collective bargaining agreement with the players’ union. The money goes to the Players’ Emergency Assistance Fund.

The incident occurred at 13:58 of the second period, with Callahan assessed a double-minor penalty for high-sticking. Callahan and Harkins were assessed penalties for fighting at the 4:12 mark of the third period.

Callahan, 25, has played in 14 games and has zero points, a minus-4 rating, 11 blocks and five hits in averaging 13:32 of ice time. He earned his first penalty minutes of the season on Wednesday.
