Joe Thornton out at least a month with rib fracture

The Toronto Maple Leafs will be without one of their top six forwards for a while.

The team announced that veteran Joe Thornton will be sidelined for a minimum of four weeks after sustaining a rib fracture while getting hit into the boards early in the third period of their 3-1 loss to the Edmonton Oilers on Wednesday.

The 41-year old has recorded one goal, one assist and a minus-1 rating in five games this season.
