Authorities said the incident happened around 1:30 p.m. at the Franklin Township Sports Complex, where an argument over a call escalated into physical violence.
"The referee strangled the coach to the point where he had visible injuries," Police Chief Matthew DeCesari said.
Police identified the referee as 47-year-old Edward McKinnie Jr. of Blackwood, New Jersey.
Investigators said McKinnie was arguing with a 46-year-old coach from the Delsea Knights when the confrontation turned physical.
According to court documents, McKinnie grabbed the coach by the neck and pushed him approximately 10 to 15 yards.
The coach was treated at the scene by EMS.
McKinnie was charged and later released, police said.
Witnesses and community members expressed concern about the incident, particularly given that it occurred during a youth sporting event.
"I think it's ridiculous. It's kids. Just let them play," said Sandy Haggarty of Franklin Township.
Action News was unable to reach McKinnie for comment.
DeCesari described the incident as part of a broader pattern of unsportsmanlike behavior in youth athletics.
"It just escalated to a point where two adults should know better," he said.
Concerns about conduct in youth sports are not isolated.
According to a survey by the nonprofit SafeSport, 46% of coaches reported experiencing verbal harassment or abuse while coaching.
The Delsea Knights declined an interview, but said in a statement posted on the league's website: "As this matter is currently the subject of both an organizational review and a law enforcement investigation, it would be inappropriate for us to comment on specific details, allegations, or individuals involved."
Residents said they hope the situation serves as a reminder to keep youth sports focused on positive values.
"Everybody is supposed to be getting along. Teaching them fundamentals of just enjoying the game," said Lamar Bronson of Clayton. "But for that to happen - people just need to calm down I guess."
McKinnie's status as a referee remains unclear. He is due to appear in court next month.
