The Ottawa Senators won't have defenceman Joe Corvo in the lineup to start the NHL season after the free-agent acquisition suffered a fractured right foot Friday night against the Buffalo Sabres. Corvo was hit on the skate by a shot from Sabres right-winger Ales Kotalik in the final minutes of the Senators' 4-3 exhibition defeat. He skated to the bench under his own power while play continued and limped off to the dressing room. After the game, the Senators announced the 29-year-old native of Oak Park, Ill., was out indefinitely. It's a big blow for Ottawa, which signed him in the off-season to help replace the void left by the departure of Zdeno Chara to the Boston Bruins.
