LINDEN, N.J. (CBSNewYork) — The Linden High School football Tigers took the practice field without one of their senior starters on Tuesday.

As CBS2’s Tony Aiello reported, Fritz Moncion was suspended following a Friday night lowlight.

Video showed him tangling on the field with a student from Immaculata.

Moncion ended up with the other student’s helmet in his hands. He swung and struck the other student on the head before tossing the helmet away.

Linden parents were shocked at Moncion’s behavior.

“He should know better than to do that,” Brian Giza said.

“There’s no place for that on the field, not at all,” Robert Roman said.

The Immaculata student is a junior, he needed 10 stitches to close a head wound, Immaculata said.

Many have praised the Immaculata student for his sportsmanship in not retaliating.

“He did a good job, very good job, lot of restraint,” Roman said.

In a statement the Linden Superintendent said the district is taking this very seriously, and “by no means is this incident a reflection on our school community, or athletic teams.”

The school refused to comment on discipline, but Moncion posted on Instagram that he was suspended “10 days from school and off the team for now,” he added, “it wasn’t purposely though.”

Immaculata sent the video to Linden police who confirmed they’re reviewing the incident for possible charges.
