Walker (upper body) will be in action versus Columbus on Monday, Marc Moser of Altitude Sports reports.
Walker was questionable to play Monday after being limited to just 11:15 of ice time against the Predators on Saturday due to his upper-body injury. In 10 games with the Avalanche, the blueliner has notched three goals, one assist and 27 shots on net, though his offensive upside is limited due to a lack of power-play opportunities.
