According to @Peter_Baugh J.T. Compher is expected to be out approximately one month due to the injury he sustained in Saturday's 6-2 win over the San Jose Sharks.
The injury mill in Colorado just churned out another one. Compher was stepping up for an injured Nathan Mackinnon on the first line but that plan has been dashed in short order. Look for Nazem Kadri to get some looks on the top line and Alex Newhook should step into a role as 2C.
