They will take forward Logan O'Connor and rear guard Patrik Nemeth's spots in the lineup, as O'Connor was reassigned to the Colorado Eagles of the American Hockey League while Nemeth is ill and won't suit up tonight.
"I like the energy that those guys bring," head coach Jared Bednar said after today's morning skate. "I like the style of play that Wilson brings up front.

"Barbs is real excited, he's obviously from the area. To get that energy and juice, as you say, back in our lineup, I think is good."
Goaltender Semyon Varlamov will start in net for the Avs tonight as they make their only trip to Montreal this season.
Below is the Avalanche's projected lineup based on the team's starting alignment from Wednesday's night contest at the Calgary Flames and the additions of Barberio and Wilson. All line combinations and defensive pairings are subject to change.
