The 24-year-old Toronto native made his NHL debut last season but played just five games before suffering a season-ending injury.
Peluso was selected in the sixth round of the 2007 draft by the St. Louis Blues. The six-foot-three, 235-pounder played in 181 American Hockey League games with Peoria, scoring 15 goals and 14 assists with 376 penalty minutes.
He was claimed off waivers by Winnipeg in January 2012.
We don't have any excuses tonight. Excuses are for losers. We've played with five defensemen before and it didn't affect us. We just had a bad second period and it cost us the game. We have to look in the mirror and blame ourselves.
— Bruins coach Claude Julien on his team's play with the loss of defenseman Johnny Boychuk
