BOSTON (CBS) – Bruins center Patrice Bergeron skated Saturday for the first time since suffering a mild concussion in Game 4 of the Eastern Conference semifinals.

Bergeron was on the ice before his teammates Saturday morning before Game 1 of the Eastern Conference finals against the Tampa Bay Lightning.

It is unlikely that the Bruins will set any timetable for Bergeron’s return. He is expected to miss at least the first two games of the series. 

Bergeron was arguably the Bruins best player over the first two rounds of the playoffs, with two goals and 10 assists in 11 games.
