Although Volchenkov (lower body) was expected to return to the lineup Tuesday against the Sharks, he ended up being placed on injured reserve.The Predators recalled Anthony Bitetto from AHL Milwaukee, and he'll presumably claim a spot in Tuesday's lineup in Volchenkov's stead. Evidently, Volchenkov hasn't progressed as fast as the team had hoped, and won't be eligible to play until Saturday's game against the Flyers.
