• Rantanen missed Sunday's game against the Central Division-leading Dallas Stars, ending his streak of 161 consecutive games.
• Despite positive early updates on Rantanen's condition, his absence was felt in the Avalanche's 7-4 loss to the Stars.

• Colorado's depth is tested as they also deal with injuries to other key players, including third-line winger Miles Wood.
