Sidney Crosby had an outpatient dental procedure in Pittsburgh on Wednesday, an anticipated follow-up from his surgery to repair a broken jaw, his agent Pat Brisson said. There remains no timetable for Crosby's return, mostly because of the uncertain nature of his recovery — an infection could delay his return. Crosby has gone four days without concussion symptoms since taking a puck to the mouth during the Penguins' home win over the New York Islanders on Saturday. There are no symptoms of post-operative infection, and Crosby remains in good spirits, Brisson said. Coach Dan Bylsma did not offer an update regarding Crosby's health.
