In the hush-hush world of playoff injury updates, speculation swirls about a player's status.

So, when Boston Bruins C Patrice Bergeron stayed on the ice to participate in practice with the rest of his teammates Monday morning — including taking line rushes with his usual wingers and rotating in on the first power-play unit — the guesswork as to Bergeron's status for Game 2 began.

Bergeron missed Boston's Game 1 loss to the Tampa Bay Lightning with a concussion sustained in the third period of Boston's series-clinching victory against Philadelphia on May 6. The Bruins' leading playoff scorer and best defensive center, Bergeron, who has a history of concussions, must go through the necessary protocol for clearance to resume activities.

Bergeron began skating Saturday. On Monday, he participated in many of the team's drills before leaving the ice early without taking part in contact drills.

Boston coach Claude Julien said there was no update on Bergeron but did not rule him out for tonight.

"As I said the other day, we're going through the protocol of what he has to go through and there's not much more to update you guys on, except that I think when he is ready to go, you guys will know it," Julien said.

"It's just something that you can't predict how quickly or how slow it's going to be. It's just one of those situations where right now you see him going through what you saw him going through (Monday), skating. But that's protocol. And right now we're not ready to make any comments because he's just going through those stages.''

The Lightning are preparing as if Bergeron will make his return tonight.
