David Krejci was not on the ice on Thursday but coach Claude Julien said it wasn’t that big of a deal.

“Maintenance, minimal maintenance,” the Bruins coach said as Krejci was given the day off.

Krejci was the only player not spotted on the sheet at Ristuccia Arena as the Bruins worked at a fast pace for 20 minutes with their power play and penalty kill units.

Andrew Ference, one of the team’s leading penalty killers, was back on the ice again and was paired with Aaron Johnson on one penalty kill unit. Julien said toward the end of his media briefing after practice that Ference has not yet been medically cleared by team doctors to play in games.

“I haven’t heard from the medical staff so I’d say the answer is ‘no,’” Julien said when asked about Ference’s medical standing as the defenseman attempts to come back from a left foot injury that sidelined him since Game 5 of the first-round series against Toronto.
