He played in the National Hockey League with the Calgary Flames, Colorado Avalanche, Carolina Hurricanes and the Tampa Bay Lightning.
In his best campaign (1994–95) he scored 40 goals and totalled 83 points in 66 games, while also amassing 201 minutes in penalties, making him a multiple threat.
Dingman, or "Dinger" as he is known colloquially, was drafted by the Calgary Flames of the National Hockey League (19th overall in the 1994 NHL Entry Draft), and played his first full NHL season for the Flames in 1997–98, where he earned a reputation as a tough customer and found himself involved as a checker and a pugilist as opposed to a scoring line player.
While he saw only limited action in his first campaign there, he gradually earned more and more ice time and in 2004, Dingman won another Stanley Cup with the Lightning.
At one point in the fight, both Dingman and Salvador had their right fists cocked, squared up, and simultaneously threw a punch.
