Defenseman Cam Fowler will be sidelined from between four to six weeks after suffering a sprained right knee in a Dec. 27 game against the Philadelphia Flyers, the Ducks said Saturday. The Ducks were initially unsure how long he might be sidelined. Fowler was injured in the first period of a 4-2 victory at the Honda Center. Fowler had three goals and 12 points and a minus-11 defensive rating in 34 games before he was hurt.
