Injured Penguins center Evgeni Malkin skated this morning but will not play today against Boston, coach Dan Bylsma said. Malkin has what is believed to be a shoulder injury. Tomas Vokoun will start in goal. Coaches often come right back with a goaltender who is coming off of a shutout, as Marc-Andre Fleury is in Saturday's 3-0 win over the Rangers, but with back-to-back games and tihs being three games four days, it's understandable that the team chose to go with Vokoun.
