On February 18, 2011, in a well-publicized trade, Kaberle was traded to the Boston Bruins in exchange for prospect Joe Colborne, Boston's first-round draft pick in 2011 and a second-round pick in 2012, conditional upon the Bruins reaching the 2011 Stanley Cup Finals or re-signing Kaberle. He ultimately won the Stanley Cup with the Bruins on June 15, 2011, prevailing over the Vancouver Canucks.
