Everyone else includes forwards Matt Calvert, Nazem Kadri and Colin Wilson and goaltender Philipp Grubauer who are out with lower-body injuries, as well as Mikko Rantanen with an upper-body injury.

"They are real close. Those are the two guys that are close," Bednar said of Burakovsky and Nieto. "Everyone else is probably mid-March."

Head coach Jared Bednar stated that both are doubtful for Wednesday's 6 p.m. MT matchup against the Buffalo Sabres. Burakovsky missed Saturday's game against the Los Angeles Kings with an upper-body injury and is day-to-day. Nieto (upper body) blocked a shot late in the game in Los Angeles and is also day-to-day.

CENTENNIAL, Colo.-- Colorado Avalanche forwards Andre Burakovsky and Matt Nieto both skated on their own on Tuesday but did not participate in the team's practice.

It was also the first team practice for new additions Vladislav Namestnikov and Michael Hutchinson, as both were acquired on Monday before the NHL's trade deadline. Namestnikov skated on a line with Pierre-Edouard Bellemare and Martin Kaut during the session. The new additions give Bednar more roster options throughout this stretch of injuries.

"Depth is a luxury," said Bednar. "Not every team has it, we haven't always had it in the past. If you don't have it, it puts a heavy burden on your top guys to contribute every night. We want that push, that internal push, where guys have to play well to stay in their slots and we've got that. I think we've got a determined group and that's why we've been able to sustain some of these injuries and continue to play well and pick up points. It can be the difference between fighting for a wild-card spot or pushing for the division, and that's what we're trying to do."

The Avs are currently second in the Western Conference and three points behind the leading St. Louis Blues with two games in hand.

While there is still no timeline on Grubauer's injury, Bednar indicated that Hutchinson is going to get a chance to play while Pavel Francouz carries the majority of the load. Francouz signed a two-year contract with the Avs on Friday and earned his first NHL shutout later that same day.

With 11 healthy forwards, defenseman Mark Barberio practiced on the fourth line with Logan O'Connor and Vladislav Kamenev. Bednar said a decision hadn't been made on whether the team was going to call up another forward from the American Hockey League's Colorado Eagles or use 11 forwards and seven defensemen against Buffalo.

The Avalanche's game against the Sabres on Wednesday at 6 p.m. will be its annual Military Appreciation Night and a nationally televised game. Below are the line combinations and defensive pairings that Colorado practiced with on Tuesday.
