Landeskog is expected to miss 4-6 weeks with an upper-body injury. Landeskog will likely miss the rest of the regular season after suffering an upper-body injury in Dallas on Thursday. This is a huge blow for the Avalanche, who are just four points out of the last playoff spot in the Western Conference right now. With Landeskog out, the Avalanche split Nathan MacKinnon and Mikko Rantanen up at Friday’s practice. Derick Brassard and J.T. Compher were with MacKinnon and Colin Wilson and Carl Soderberg were skating alongside Rantanen.
