The NHL has fined Boston Bruins rookie defenseman Michael Callahan $2,018.23 for cross-checking Anaheim forward Jansen Harkins during the Ducks' 6-2 home victory on Wednesday.

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 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 Wednesday.
