The Edmonton Oilers have made a move just before the roster freeze, placing forward Nathan Walker on waivers. In a corresponding move, the team has recalled Anton Slepyshev from the minor leagues and placed Oscar Klefbom on injured reserve. Walker was only claimed by the Oilers earlier this month, and will now be available once again to the rest of the league. If reclaimed by the Washington Capitals without any other team putting in a claim, Walker could be sent to the minor leagues immediately. Walker, the first Australian to be drafted and play in the NHL, made his debut earlier this season when he suited up for the Capitals.
