Professional career

He began his career with the Rochester Americans of the American Hockey League (AHL) where he would play for two seasons before being called up to the Buffalo Sabres in 1991. He stayed with Buffalo until he was traded to the Edmonton Oilers for Scott Pearson on April 7, 1995.

Sutton played parts of two seasons for Edmonton in between stints with the Worcester IceCats. He was traded to the St. Louis Blues along with Igor Kravchuk for Jeff Norton and Donald Dufresne on January 4, 1996. He only played a total of seven games for the Blues spending the rest of the season with the IceCats.

Sutton was traded to the New Jersey Devils with St. Louis' second-round choice (Brett Clouthier) in the 1999 NHL Entry Draft for Mike Peluso and Ricard Persson on November 26, 1996. Sutton would spend the entire 1997 in the minors between the Manitoba Moose of the International Hockey League (IHL) and the AHL's Albany River Rats.

Sutton played 13 games for New Jersey in the 1997–98 season before being traded to the San Jose Sharks with John MacLean for Doug Bodger and Dody Wood on December 7, 1997.

Sutton was claimed by the Washington Capitals in the Waiver Draft on September 27, 1999 before being sent back to New Jersey for future considerations on October 5. Sutton again played the majority of the season in Albany before being called up to the Devils for the playoffs. He would help New Jersey win the Stanley Cup in 2000. Sutton's name was included on the Stanley Cup in 2000 even though he did not qualify as he had played only six regular season games, and did not dress in the playoffs.

Sutton signed as a free agent with the New York Islanders on July 5, 2001. He split the 2001–02 season between the NHL and the Bridgeport Sound Tigers of the AHL.
