Niemi will serve as back-up to Alex Stalock in Wednesday's game against the Flames, according to Curtis Pashelka of the Mercury News. Niemi is likely to get the net on Thursday though, with the Sharks on the front end of a back-to-back on Wednesday. The decision to start Stalock isn't a shift in focus for the team, but an attempt to not work Niemi into the ground before the playoffs like they've done in previous seasons.
