Boston Bruins defenseman Johnny Boychuk will be out three to seven days with a back sprain, general manager Peter Chiarelli told NHL.com on Saturday.
Boychuk left 4:28 into Thursday night's game against the Montreal Canadiens after being taken into the boards by left wing Max Pacioretty. He was taken off the ice on a stretcher. Pacioretty was given a two-minute penalty for boarding.
Boychuk was briefly hospitalized in Montreal before joining the Bruins for their flight back to Boston, where they host the Pittsburgh Penguins on Saturday night.
Pacioretty said he was not trying to hurt Boychuk.
"I feel terrible," he said. "I've been in that situation before. As you can tell from my game right after that, it definitely rattled me a lot. I wish him nothing but the best."
Boychuk has a goal and five assists in 27 games this season. He is third on the team with an average ice time of 20:19 per game.

New USC coach Steve Sarkisian is bringing three assistants from Washington.
USC lured Sarkisian from Washington, hiring him on Monday.
Johnny Nansen, Keith Heyward and Peter Sirmon will rejoin Sarkisian at USC, though their specific responsibilities will not be known until he completes his staff. At Washington, Nansen served as running backs coach/special teams coordinator, Heyward was secondary coach and Sirmon was linebackers coach.
"I'm fired up to have Johnny, Keith and Peter join the staff," Sarkisian said in a statement. "We're on the right path in putting together one of the best coaching staffs in America."
Sarkisian announced that Trojans wide receivers coach Tee Martin will be retained.
It has been reported that Justin Wilcox, Sarkisian's defensive coordinator at Washington, will interview for the coaching job at Boise State. That job opened up when Chris Petersen left to take over at Washington. Otherwise, Sarkisian would like to keep Wilcox.
The Seattle Times reported Friday that the buyouts for Sarkisian and the three assistants exceed $1.5 million. If Wilcox leaves, that total would surpass the $2 million mark.
Former flyweight and junior flyweight champion Jacob Matlala died Saturday, a family spokesman announced. He was 51.
The South African was a four-time world champion in both divisions. Matlala, known as "Baby Jake," was one of Nelson Mandela's favorite fighters.
Mandela, the former President of South Africa, died Thursday. Mandela attended Matlala's last bout in 2002 and Matlala gave him one of his belts.
"Another great fighter has died ... Go well little man, you'll be missed," wrote Rodney Berman, Matlala's former promoter, on Twitter.
The 4-foot-10 Matlala was one of South Africa's most popular athletes. He won WBO flyweight and junior flyweight titles, and IBA light flyweight and WBU junior flyweight belts during his 22-year career.
