With Barrie expected to miss at least 12 contests, the Avs will look internally to fill his spot, at least in the short term.
His usual defensive partner, Patrik Nemeth, will play with Mark Barberio for the Avalanche's rematch outing this evening versus the Coyotes, while Samuel Girard and Johnson will help shoulder the load on the power play.
Barrie was leading the club's top power-play unit, which was helping the club click at a 19.2-percent success rate overall and 26.6 percent at home--fifth best in the NHL.
Girard and Johnson were splitting time on the second man-advantage group, but Bednar said that Johnson will be on the first unit for the time being, while Girard will man the second group.
"I think we all have to step up, all the defense, to make sure to help cover his spot," Girard said. "Barrie was bringing a lot of offense for us, so we have to be better in the three zones, offensively, defensively and neutral zone. We have to be better everywhere for him."
