Kampf (upper body) has been ruled out for Saturday's game against the Blue Jackets, Terry Koshan of The Toronto Sun reports.
Kampf sustained an upper-body injury during Wednesday's game against the Panthers, and head coach Craig Berube said Friday that the 30-year-old is considered day-to-day. Kampf will have a few days to recover before the Maple Leafs face Florida on Tuesday, but it's not yet clear whether the team expects him to be available for that matchup.
