Patrice Bergeron, who suffered a concussion vs. the Senators on April 2, participated in an optional skate Friday morning with 13 teammates at Ristuccia Arena. The Bruins center engaged in several net-front battle drills, looking nimble and strong in his second time back on the ice in as many days, before he was last to depart the sheet at 12:25 p.m. along with assistant Doug Houda.

“He just did some regular drills, just like he was going to be in the game,’’ said goaltender Anton Khudobin, who worked in net against Bergeron. “He stayed in front of me and we tried to do some exercises like he was going to be in the game.

“I tried to do what I’m going to do and he tried to do what he’s going to do. It was normal.’’

Asked if Bergeron looked better, Khudobin replied, “Oh, of course, of course. Hopefully, he’s getting better, but all the questions are still on the doctors.’’

Although Bergeron traveled with the team to Raleigh, N.C., for Saturday night’s game against the Hurricanes, coach Claude Julien said Bergeron was not expected to play.

“Bergy will travel with us,’’ Julien said. “He’s skating now and he’s skating with us and he’s better off to work out with us than to stay behind.’’

Asked if Bergeron would be available to play, Julien replied, “I don’t think so. We’re certainly going to be cautious with him. He’s had a history [of concussions] and we’re not going to take a gamble with it.

“We’re being extremely careful with Bergy and we’re going by the protocol. Never will this organization risk a player’s health for any reason. But he felt pretty good this concussion was moderate, and from what I’ve been told, it’s had a zero [effect] on the major one that he’s had and a zero issue on his brain.’’

The sight of Bergeron on the ice, putting himself through a rigorous workout, was an encouraging sign to his teammates.
