The Bruins were tied for the most games played (26) going into Saturday’s divisional tilt against the Detroit Red Wings. That fact is showing up in the worst way possible.

Already besieged by injuries, the B’s added another body to the list with right shot defenseman Henri Jokiharju being moved to injured reserve with an unspecified injury and Michael Callahan was brought back up from Providence.

Jokiharju joined the “unavailable” list that included David Pastrnak (unspecified), Charlie McAvoy (face), Viktor Arvidsson (lower body), Jordan Harris (ankle) and Matej Blumel (lower body).

“It’s a tricky injury. It could be days, could be…I don’t know. So we have to manage that so Callahan will be back in,” said coach Marco Sturm.

Pavel Zacha, who missed Friday’s game with an upper body injury, did take part in the optional morning skate and was termed a game-time decision.

The Jokiharju injury leaves the B’s with just one healthy right-shot defenseman, Andrew Peeke.

With the condensed schedule due to the lengthy Olympic break coming up in February, most teams are dealing with some level of injury. But for the B’s, both the volume and the caliber of players knocked out of the lineup has been particularly crippling the last couple of games.

“It’s hard to say (the cause) but we have had a lot more games this year because of the Olympics. Way more games, right after each other and all the flying…That’s why, I’m assuming. It’s been a lot of games at the start of the season so hopefully everyone’s going to get into the rhythm and won’t have more injuries going forwards,” said Zacha.

Arvidsson agreed that the schedule has been rough.

“It’s been hectic and we’ve played (26) games already. I think with a long training camp and going into a season where there’s a lot of games before the break in February, I think a lot of teams have faced some adversity. Our team is one of them. We’ve just got to stay as consistent as we can through everything. We just have to keep playing,” said Arvidsson….

Zacha said that he suffered his injury on a faceoff early in the win on Long Island on Wednesday.

“It just got worse progressively, so I decided to take the day (on Friday) to try and get it better,” said Zacha. “With injuries, you want to get back as soon as you can. It was just unlucky that it was also (Pastrnak) and we’ve been struggling the last couple of weeks with injuries. As a player you want to get back as quick as you can. It’s hard to watch the games when you can’t help the team.”

While Pastrnak is special player, Zacha is an all-situations, all-purpose presence for the B’s…

Arvidsson got back on the ice for the first time during the B’s optional morning skate at the Garden on Saturday.

“I was just trying to get into the rhythm of everything, so we’ll see when I can start playing. But there’s not a lot of practice. It was a good day to get out there,” said Arvidsson. “It was good. I thought I could handle some speed and stuff and it was good to have other guys out there, feel that, too, and have a lot of bodies there.”…

There was no more clarity on Pastrnak’s injury but Sturm remained hopeful.

“I don’t think it’s going to be long-term, so we’ll see day-by-day,” said Sturm.

“I’m not going to lie, it hurts you, not just 5-on-5 but on the power play, you could see it. On Friday, we were not really a threat we’ve been all year long. Those guys, you can’t replace them. That’s why you can’t blame the (Georgii) Merkulovs and the (Riley) Tuftes because they’re just not David. But everyone’s going through it and we have to manage that, too. And somehow we have to play better defensively again, even better.”….

McAvoy — out since November 15 after taking a puck to the face in Montreal, causing an injury that required surgery to repair — was on the ice prior to the team’s morning skate, sporting a bubble with the chin protector underneath. Sturm said there is no timetable yet.

“It was definitely nice to see him on the ice today, with a smile. He looks great. I think he looks better than before. It was nice to see him. We all feel for him. It’s been a tough road for him, but he’s been such an important piece for our team,” said Sturm. “They’re working really hard (to get him back), not just (the face) but also his body. He didn’t move since Montreal, lost a lot of weight, so there’s work to do.”…

Jonathan Aspirot was sporting four stitches and a swollen cheek after taking an errant stick on Friday but he was good to go on Saturday.
