Both Torey Krug and Adam McQuaid were missing from the B’s practice ice on Tuesday morning, and are “day-to-day” leading up to Thursday night’s game against the Montreal Canadiens, according to coach Claude Julien. McQuaid has re-aggravated a lower-body injury believed to be a groin issue that kept him out of the lineup for eight games. Krug has a “minor body” ailment, according to coach Claude Julien. The Bruins called up Kevan Miller on emergency recall from the AHL with the expectation that he’d be in the lineup in place of the similarly-skilled McQuaid. The 26-year-old Miller was more than happy to be back after logging three NHL games last week, playing in a pair of AHL games against Norfolk and Hershey over the weekend, and then reporting right back to Boston for duty on Tuesday. He was excellent in his three games with the B’s while McQuaid and Dennis Seidenberg were out of the lineup, and he quickly earned the confidence of Bruins coaches in key situations. “We got in from Hershey on Monday, and then came right back up here,” said Miller. “It’s obviously a confidence booster, and I’m just waiting to be ready when I get called.” Julien was vaguer about Krug's injury, who took a couple of heavy hits over the weekend in the win over Columbus and also blocked a shot with his foot late in the game. The expectation was that he might still be available for the game with the Habs, but Matt Bartkowski stands in wait if the offensively-gifted Krug can’t play at the Bell Centre.
