Bruins general manager Peter Chiarelli said during a Boston radio appearance Wednesday morning that star center Patrice Bergeron, who suffered a concussion last Tuesday night, is practicing and is “on the road to recovery.’’

“So it looks good,’’ added Chiarelli, who spoke on 98.5 The Sports Hub. “He’s working out and things are looking good.’’

Bergeron suffered the fourth concussion of his career when he was bumped midway through the second period last Tuesday by Ottawa’s Colin Greening. It appeared to be a light hit, but a pal of Bergeron’s said over the weekend that the 27-year-old was left with a considerable bruise under his left ear and on his neck.

Bergeron was examined Friday by Dr. Robert Cantu, the well-known concussion expert based in Concord, Mass. Bergeron’s friend said the Selke Trophy winner was very encouraged after meeting with Cantu and was optimistic about returning to the lineup.

Bergeron did not make the trip here and his practice sessions presumably have been in Boston. Chiarelli, also not here for the game, did not specify the location or nature of the workouts during his radio appearance.

Coach Claude Julien sounded encouraged by the news on Bergeron following the morning workout before facing the Devils Wednesday night.

“Any time a guy starts to do something, it’s a step in the right direction,’’ Julien said.
