As much as it was a relief for the Bruins to have Patrice Bergeron back in the lineup for Game 3 of the Eastern Conference finals Thursday night, it was even more encouraging when he woke up symptom-free Friday morning. The forward missed the first two games of the series against the Lightning with a concussion, but he showed no ill effects in Game 3. Bergeron participated in the team's optional practice Friday morning and afterward said he's feeling good.
