Peter Mueller the up and coming center for the Colorado Avalanche suffered another concussion in the preseason opener against the LA Kings. Mueller was concussed last season, which ended his year, and was hopeful that he would have a full year this season with a new helmet that could lessen the blow to the head. That helmet had not arrived yet to Denver, now Mueller is out for an undetermined time, and the Avalanche are looking for a center once again.
