Devils' Smith suspended two games for slashing
Konecny was also fined $5,000, the maximum allowable under the collective bargaining agreement, for cross-checking Smith.
The incident occurred late in the third period of the Devils 4-3 overtime victory over the Flyers.
While skating towards the bench, Konecny hit Smith across the back with his stick before the Devils defenceman retaliated with a slash across the chest, causing the Flyer to double over in pain.
Smith was assessed a minor penalty for slashing on the play while Konecny did not receive a penalty for the altercation.
The Devils went on to win the matchup 4-3 in overtime.
