Elias, who received a minor boarding penalty on the play, said he was notified by his former teammate, league disciplinarian Brendan Shanahan, of the fine via telephone conversation Friday.
"I talked to him and he explained why," Elias said. "The way he looked at it, what he had an issue with was my follow-through. I get it."
Elias, who played with Shanahan in New Jersey, suspected his reputation as a clean player probably helped him to escape further discipline.
"He knows me. He played with me. He knows I'm not a dirty player," Elias said.
With the Devils already decimated on defense, coach Pete DeBoer said he was relieved his leading scorer avoided suspension. Elias, 35, has 18 goals and 30 assists in 49 games for the Devils this season.
"With where we're at, that's the last thing we need," DeBoer said. "He can afford the fine, too."
The $2,500 is the maximum allowed, per the rules of the collective bargaining agreement. The money will go to the Players' Emergency Assistance Fund.
