The fine comes in response to both players committing a second act of diving and embellishment this season in accordance with new rules designed to more strongly penalize players who try to use diving to draw penalties.
The new rules came into effect this season and require that players be given a warning after a first offence followed by a fine for each subsequent offence.
Nyquist was warned after an incident Nov. 28 in a game against the Devils. His second offence happened during a Dec. 29 game against Boston where his embellishment led to a tripping penalty against Bruins forward Chris Kelly.
Trochek was similarly warned after his actions were flagged by the NHL's operations department during a Dec. 12 game against the Red Wings. He did it again during a game on Jan. 4 against the Capitals leading to Washington defenceman Brooks Orpik getting a slashing penalty.
The NHL's new rules are supposed to deal with the diving problem, showing the league is not taking the issue lightly.
