Tkachuk was absent from the morning skate on Tuesday and will not play against the Buffalo Sabres due to an upper-body injury. In Ottawa's previous game, Tkachuk was playing on a line with Shane Pinto and Ridly Greig, a spot that has been filled by Michael Amadio. The 25-year-old Tkachuk has 55 points (29G / 26A) in 71 games this season.
