Middle linebacker Daryl Smith had a big day Sunday, returning an interception for a touchdown Sunday and leading the Ravens with 10 tackles. Plus, his wife gave birth to a baby girl early Monday morning. "Probably nobody knew about that, that's how quiet he is," said Harbaugh, who celebrated his 51st birthday Monday. "And she does share a birthday with yours truly. It was a glorious day for the Smith family." ... Marcus Spears started in place of Canty and finished with three tackles, two for losses. Spears also started the season-opener against the Denver Broncos when Arthur Jones was out with an irregular heartbeat. "You make a couple of standout plays and people think it's a great game, but it's never as bad or as good as people think," Spears said. "I try to keep that mentality and do my job."
