The Bruins did not start the new season the way they had envisioned. Not only were the B's without their top player Patrice Bergeron, out day-to-day with a lower body injury, and defenseman Torey Krug (broken jaw), but it was learned Thursday night that David Backes would be out at least three to four weeks after being diagnosed with diverticulitis and has been undergoing treatment at Mass. General by team internist Dr. David Finn. He will be re-evaluated in approximately two weeks but will be out for longer than that. Diverticulitis is an inflammation or infection in one or more small pouches in the digestive tract. While Backes could be missed for a month or more, the hope for Bergeron is that he'll be able to take advantage of the B's light early schedule and be back in the lineup for the next game, the Columbus Day matinee against the Colorado Avalanche.
