Report: NHL closely reviewing Wilson's hit on Dumoulin

Tom Wilson's hit on Brian Dumoulin is under scrutiny.

The Washington Capitals forward caught the Pittsburgh Penguins defenseman with a hit to the head in Sunday's Game 2, a collision that went unpenalized.

Now, the NHL Department of Player Safety is in the process of closely reviewing the incident, a league source told Isabelle Khurshudyan of The Washington Post.

Since Wilson was suspended twice in the preseason, he is considered a repeat offender, which could potentially lead to a stiffer punishment if the league decides the hit warrants action.

That history, however, does not factor into whether there should be supplemental discipline to begin with.

Dumoulin was unable to return to the game, and there's no word yet on his status for Game 3.
