Carlo Colaiacovo (pronounced /ˌkoʊleɪ.əˈkoʊvoʊ/) (born January 27, 1983) is a Canadian ice hockey defenceman currently playing for the St. Louis Blues of the National Hockey League (NHL). Colaiacovo also has an identical twin brother, Paulo Colaiacovo, who is a professional ice hockey goaltender.
Colaiacovo was drafted 17th overall by Toronto in the 2001 NHL Entry Draft. Colaiacovo has been bothered by injuries that have hindered him from becoming an NHL regular, but many still consider him to be a good prospect. He scored his first career NHL goal on November 8, 2005, against the Washington Capitals.
On January 23, 2006, Colaiacovo missed a hipcheck on Václav Varaďa in a game against the Ottawa Senators, smashing head-first into the boards. He was taken off the ice in a stretcher. The injury was a major concussion, and he missed the end of the 2005–06 NHL season.
