Ottawa Senators coach Paul MacLean was pressed and pressed on the status of star centre Jason Spezza Wednesday morning. He offered little more than the fact that Spezza is "still being evaluated" and that he won't be playing against the Montreal Canadiens Wednesday at Scotiabank Place. "We'll have an update as it becomes available," MacLean said. When asked if it could be an injury that sidelines Spezza for an extended period, the Senators coach said, "we're waiting on the evaluation. We don't know." When the topic of Spezza possibly having an out-of-town expert check out his injury – as was the speculation during Tuesday's 3-2 win over the Washington Capitals – MacLean was again not forthcoming. "I'm not sure," he said. "He's being evaluated." The Senators reluctance to provide additional information is fuelling concerns that the injury could be serious, perhaps related to his back, and that Spezza could be missing from the lineup for awhile. Spezza has had issues with his back in the past. He had surgery following the 2006 season and missed action late in the 2007 season when a back problem occurred while he was carrying groceries.
