Career
Starting with the 1994-1995 National Hockey League season, he wore uniform number 12, and, since the 1987-1988 National Hockey League season, he wore a helmet while refereeing National Hockey League games. Koharski began his officiating career in the World Hockey Association in 1975, as a 19-year-old linesman. (He is the final player or official from the WHA to be involved in professional hockey in an on-ice capacity) In 1976, he was signed by the American Hockey League while working with a local dairy farm, for which he was milking cows.
He began his National Hockey League career 1977, as a linesman, before moving to the referee role in 1980.
He was the league"s second-most senior official, behind only referee Kerry Fraser. On April 8, 2006, Koharski reached the 1,500-regular-season-game milestone when he officiated a game between the Pittsburgh Penguins and the Tampa Bay Lightning.
During the National Hockey League player lockout of 2004-2005, Koharski officiated a charity game between former players from the United Hockey League, as part of their All-Star Game festivities. On March 24, 2009, it was announced that Koharski would retire as an National Hockey League referee at the end of the 2008-2009 National Hockey League season.
However, he will stay on with the National Hockey League in a supervisory or instructional position.
In total, he officiated 1,719 regular season games and 248 playoff games. Koharski is perhaps best known for an incident that occurred following Game 3 of the 1988 Prince of Wales Conference Finals between the Boston Bruins and the New Jersey Devils at Brendan Byrne Arena. Devils coach Jim Schoenfeld was infuriated with Koharski’s performance and waited for him in the hallway near the officials’ dressing room.
During the course of the argument, which became increasingly heated, Koharski lost his balance and fell down.
Believing that Schoenfeld pushed him down, Koharski yelled several times after he left saying "You"re done", implying that he would be suspended over the incident, and said he hoped the incident was on tape. Schoenfeld responded by yelling in Koharski"s direction, "Good, because you fell, you fat pig! Have another doughnut! Have another doughnut!" (A videotape of this incident recorded by WABC has become part of sports television lore ever since, usually when discussing coaches losing their tempers)
The National Hockey League responded by suspending Schoenfeld, but the Devils took legal action and were granted a court order staying the suspension.
The National Hockey League Officials" Association stood by Koharski. Its members said they would not take the ice in the next game between the Devils and the Bruins if Schoenfeld was allowed to coach.
This resulted in the National Hockey League being forced to use low-level replacement officials for the game, with the two linesmen wearing Devils-coloured Cooperall long pants (at the time, green pants with red-and-white stripes), along with white helmets and yellow practice jerseys over their street clothes.
The incident was parodied in the movie Wayne"s World, in which Frederick Coffin played a police officer named "Officer Koharski."
According to Schoenfeld in an interview with Canadian sports network TSN in 2013, Koharski, who had been overweight at the time of the incident, eventually lost weight.
