The coach who witnessed his player eat a VICIOUS cheap shot elbow tells TMZ Sports he couldn't be happier his team did NOTHING in retaliation.
The video's insane ... Fitchburg State was playing Nichols College (both D-III teams) Tuesday night in Massachusetts ... when FSU's star Kewan Platt intentionally elbowed Nate Tenaglia ... sending him to the deck.
A lot of people wondered where the hell Nate's teammates were ... and why didn't they step up and return the favor?
Nichols head coach Scott Faucher knows why .
