A New Jersey high school lacrosse coach has been fired after hitting a rival player in an on-field altercation on Saturday.

According to Mike Kinney of NJ Advance Media, an assistant coach at Don Bosco Prep, the top-ranked boys lacrosse program in New Jersey, has been relieved of his duties after an on-field altercation in which he shoved a player from rival St. Joseph Regional High School. The firing of the assistant coach was confirmed in a statement by Don Bosco Prep athletic director Marcin Szorc.

“Very unfortunate,” Szorc said. “Don Bosco does not condone any violence towards coaches, fans, or opposing players. The coach in question had been relieved of his duties before the game concluded. An internal investigation has begun to prevent such things from happening in the future.”

Per Kinney, an exchange of words between a Don Bosco and St. Joseph player escalated into a scuffle. Coaches from both Don Bosco and St. Joseph stepped onto the field to de-escalate the situation, but the Don Bosco assistant coach instead pushed the St. Joseph player to the turf with two hands to his chest.

The incident was caught on video and can be seen below.

Don Bosco went on to defeat St. Joseph by a final score of 20-0. Both head coaches refused to comment on the incident postgame. The altercation has been referred to the New Jersey State Interscholastic Athletic Association and the North Jersey Interscholastic Lacrosse League.
