Been there, had the shirt ripped off.
We had staff/Sixth games at ours, until they stopped for the same reasons.

However, the staff contained a high proportion of priests. Irish priests, which means hyperviolent hurling/GAA veterans. 30 seconds in, the headmaster flumped the head boy. After the first scrum, the Head of Maths had an eyebrow half off. 15 minutes, and the match was abandoned when the staff coach ran on and kicked the No 8 in the bollocks from behind.
