Daniel Carcillo was born January 28, 1985 in King City, Ontario. Pittsburgh's third round, 73rd overall selection in the 2003 NHL Entry Draft, Carcillo is a graduate of the OHL's Sarnia Sting and Mississauga Ice Dogs.
A strong power forward, Carcillo made his junior hockey debut with the Sarnia Sting and was named to the second team OHL All-Rookie Team after recording 66 points in 68 games. He would continue to produce offensively in the OHL over the next few seasons with Sarnia and Mississauga before making his professional hockey debut with the Penguins' AHL affiliate, the Wilkes-Barre/Scranton Penguins.
After a penalty filled rookie campaign, Carcillo returned for another year in Wilkes-Barre. He appeared in 52 games with the baby Pens before his parent club shipped to the Coyotes at the NHL trading deadline for Georges Laraque. He would compete in 18 games with the Coyotes and finish his year with the club, making his NHL Debut on March 3rd, 2007.
On March 4, 2009, the NHL's trade deadline, the rugged forward was traded to the Philadelphia Flyers in exchange for Scottie Upshall and a second round draft pick.
In Philadelphia, Carcillo continued to make a name for himself as one of the toughest opponents in the league. In 153 games in the "orange and black" over the course of two and half seasons, he recorded a whopping 414 penalty minutes.
On July 1, 2011, Carcillo's time in Philadelphia would come to an end. As an unrestricted free agent he signed a deal with the Chicago Blackhawks.
Carcillo would miss much of the 2011-12 season due to a knee injury suffered on January 2, 2012 against the Edmonton Oilers. When healthy however, Carcillo continued to play his brand of "in your face" hockey. In 28 games for the Blackhawks he would compile 82 penalty minutes.
The Blackhawks would dominate the lockout-shortened 2012-13 season, rolling through the NHL's regular season and capturing the Presidents' Trophy. Carcillo however would appear in just 23 games for the club, scoring twice and adding just a single assist.
The playoffs were more of the same and though pushed to the limit by the Detroit Red Wings in the second round, the Blackhawks would prevail and eventually earn the fifth Stanley Cup title in franchise history, the first in Carcillo's career.
On July 16, 2013, Carcillo was traded to the Los Angeles Kings in exchange for future considerations.
