Avalanche's Vladislav Kamenev: Needs shoulder surgery

Kamenev will require shoulder surgery, Rick Sadowski of NHL.com reports.

We don't have a timetable for Kamenev's return, but shoulder surgery will leave him out indefinitely, and it will probably be a while. With the 22-year-old out of the lineup, the Avalanche will need to call somebody up to replace him on the roster.
