Groin problems are becoming a bad habit for the Ottawa Senators in the pre-season, with the latest victim being the team's No. 1 defenceman. Wade Redden left the first period of the Senators' game against the Toronto Maple Leafs on Sunday after his groin tightened up and did not return. He is the third Senator to have groin troubles this pre-season. Captain Daniel Alfredsson and forward Peter Schaefer have also been bothered by groin pains, as the Senators are in the midst of a busy nine-game exhibition schedule.
