Boulton out indefinitely
Boulton and Boulerice began slugging it out 4:47 into Buffalo's 4-2 victory. Boulerice whipped his smaller combatant around and Boulton dropped to the ice in obvious pain.
The 6-foot, 224-pound Boulton did not return. He has just one assist with 53 penalty minutes and a minus-2 rating in 29 games this season, his fourth in the NHL.
Boulerice was called for roughing later in the game, giving him a team-high 87 penalty minutes.
