BOSTON - Torey Krug is day-to-day with a lower-body injury.
The defenseman will not be available for the Bruins' final game of the regular season on Saturday against the Washington Capitals at TD Garden (3:00 p.m. ET, NESN, 98.5 The Sports Hub).
Krug left Thursday's night's game with the injury. He did not practice with the team on Friday at Warrior Ice Arena.
Forward Noel Acciari was also absent from the practice. He is day-to-day with an upper-body injury, according to Interim Head Coach Bruce Cassidy.
Following the practice, Cassidy did not have further information on Krug's status heading into next week, when Boston will begin postseason play.
"He'll be out [Saturday] that much we know, and then from there, day-to-day," said Cassidy.
With Krug's skill set, he will not be easily replaced.
"Well, we're not going to be able to replace what he does," said Cassidy. "He's a special talent - power play, first pass, breakout, neutral zone transition, all of those things - so the onus will be on us to make sure we make the necessary reads in our breakout."
"And the power play, you know Johnny Liles has certainly been on there, Zee's done a good job, recently we've mixed him in. If Colin Miller draws into the lineup, he's been on it, so there are options there," said Cassidy.
"We're going to miss his ability to get us going on offense in a hurry. But having said that, we've got good puck movers back there and it's the way it is this time of year - you get an injury, it's next man up who's got to get in there, and play to his strengths without trying to be something that he's not, so that's what we'll ask of that position."
"Losing a guy like Torey's never easy," said Captain Zdeno Chara. "And he's obviously's been a big part of our team's specialty teams and obviously we don't know the status of the injury, but hopefully he's going to be back and on the ice soon."

Liles has been in the lineup frequently down the stretch, and now he will be relied upon even more in Krug's absence. He's still keeping his same approach, though.
"Same way it's been all year, just come in, put my head down and try and work hard and I'll be ready wherever they put me, wherever they feel that I'm needed," said Liles. "Hopefully Torey's back soon, and it's up to not just myself, but everybody on the D corps to pick up the slack."
Forsbacka Karlsson Could Make Debut
Forward Jakob Forsbacka Karlsson has received immigration approval, and is available for Saturday's game against Washington.
"He's a possibility for sure," said Cassidy. "With some of our injured guys getting much closer to playing, we'll have some decisions to make [Saturday] morning, but he could certainly get in."
Forsbacka Karlsson had the opportunity to skate in warmups on Thursday night for the first time.
"It's a very special feeling, putting on the jersey and getting out there," said Forsbacka Karlsson. "It's special, for sure."
"I'm ready to go, absolutely, but that's obviously up to the coaches."
While the lineup is not yet for sure up front and on the back end, Anton Khudobin is slated to start between the pipes. Stay tuned to Twitter @NHLBruins on Saturday for lineup information.
