- After battling an upper-body injury throughout the last week, Toronto Maple Leafs defenseman John Klingberg will be ready for the team’s season-opening contest against the Montreal Canadiens on Wednesday, head coach Sheldon Keefe tells NHL.com’s Dave McCarthy. Klingberg, the team’s key free agency addition to their top four on defense, says he feels good enough to play in tomorrow’s preseason finale against the Detroit Red Wings but that he’s “going to listen to the doctors, I think they’re smart enough to know.” The veteran 31-year-old power-play quarterback is expected to see reps on the team’s top man-advantage unit to start the season, allowing longtime Leaf Morgan Rielly to help bolster the second power-play unit.
