With the Avalanche trailing, 5-0, late in the second period, Koci crushed Capitals defenseman Mike Green from behind, and then threw down with Green's teammate, John Erskine.
Koci was issued a five-minute major for boarding, a five-minute major for fighting and a 10-minute game misconduct. Erskine, meanwhile, received five minutes for fighting a two-minute instigator penalty.
The next concern for Koci is whether or not he'll receive additional punishment from the NHL. Seeing as how it was a hit from behind, combined with the fact there was an injury on the play, it's possible -- if not likely -- that he'll receive something.
