The Senators are already without three blueline regulars in Jake Sanderson (upper body), Nick Jensen (knee), and Thomas Chabot (upper body), and added Kleven to the list on Thursday. The 24-year-old Kleven has seen a massive uptick in playing time as a result of team injuries, but exited Thursday's 4-1 win over the Buffalo Sabres early in the first period after taking a puck to the face.
