Carcillo was given the large ban Wednesday, two nights after he sent Gilbert into the boards in the second period of the Blackhawks' 4-3 home victory over the Oilers. Carcillo was given a major penalty for boarding and was ejected from the game.
Gilbert sustained an undisclosed lower-body injury and didn't play in Edmonton's 4-3 loss to Buffalo on Tuesday night.
Carcillo, suspended in October for two games for an illegal check against Carolina defenseman Joni Pitkanen, was treated as a repeat offender. He will lose $66,158 in salary after forfeiting $8,378 for the earlier ban.
He will be eligible to return Jan. 18 when the Blackhawks host Buffalo.
