Hamilton will be out two-to-four weeks with a lower-body injury.
The Bruins defenseman continue to drop like flies as now they are down to just five healthy defensemen. Hamilton play just 5:58 before leaving Sunday's game vs. the Maple Leafs. The Bruins are unsure if Johnny Boychuk will be available tonight. Unless someone is recalled soon, the Bruins will play with five D-men if Boychuk can't go.
