Avalanche's Gabriel Landeskog: Undergoes surgery

Landeskog underwent successful knee surgery Tuesday, Adrian Dater of Colorado Hockey Now reports.

The physicians did not provide a timetable for when Landeskog could return to the ice, but the forward was "confident" he'd return for the playoffs if not sooner. The Avalanche could place Landeskog on long-term injured reserve, which would open up $7 million in cap space for a possible acquisition at the trade deadline. Philadelphia's Claude Giroux has been linked to Colorado over the past month.
