Michalek suffered a lower body injury and did not travel with the team for Monday's game against the Avalanche, Craig Morgan of FoxSports Airzona reports.Michalek skated for 17:53 worth of ice time in the team's last game Saturday against the Rangers, so the exact nature of when and where the injury occurred are not entirely clear. He's currently listed as day-to-day, and since the Coyotes have four days off after Monday's contest, it's possible he'll be able to return on Saturday against the Lightning.
