Vlasic (upper body) didn't take the ice for morning skate and looks like he'll be out for Thursday's game against the Wild, CSN Bay Area's Kevin Kurz reports. With Vlasic unavailable, rookie Mirco Mueller is slated to take his spot on the top pairing and play big minutes next to Justin Braun. The Sharks were labeling Vlasic as questionable heading into Thursday, so there would seem to be some optimism that he's not dealing with a long-term injury. He could return to the lineup as soon as Saturday's tilt with the Predators.
