The Boston Bruins are riding high, but the same cannot be said for defenseman Kevan Miller, who was downgraded from day-to-day to week-to-week with an upper-body injury, according to B's coach Bruce Cassidy.

"He got a little bit of bad news the other day with his MRI," Cassidy said following Monday's practice at Warrior Ice Arena. "We didn't think it was much. They found something there, so it's a little more serious than we first thought.

"So he's been classified as week-to-week as opposed to day to day."

On the shelf from the last three games (all wins for the Bruins), Miller's absence will continue to be John Moore's gain, as the first-year Bruin skates on the Black and Gold's third-pairing opposite Matt Grzelcyk. It's been an OK pairing to date, with even shot totals for and again, and with Grzelcyk continuing to be perhaps the B's most underrated defenseman.

Miller's downgrade also came on a day that saw the Boston blue line go through a separate scare, as team captain Zdeno Chara took a puck to the face during a penalty-kill drill. Chara would receive a couple of stitches for his trouble, but is expected to be fine and ready to go for Tuesday night's head-to-head with the Carolina Hurricanes.

The Bruins enter Tuesday riding a 16-game point streak.
