The incident happened in the final seconds of the National Junior College Athletic Association [NJCAA] championship game between E.C.C. and Dakota College.
Brandon Day, a freshman who graduated from West Seneca, was in the penalty box and promptly left the box during a pause in play.
According to WKTV-TV, SUNY Broome Police are investigating the incident, and quoted Erie County Executive Mark Poloncarz as saying Day was charged with assault.
One college hockey player went from the sin bin to the slammer Sunday night.
The referee was injured by the brutal check and officials called off the game prematurely.
It wasn't clear what motivated Day to storm out of the penalty box. Dakota was assessed 18 minutes in penalties in the game for nine minor infractions.
At that point, officials chose to end the game.
It was the 10th NJCAA title for Bottineau, which also defeated ECC in last year's championship game in Binghamton, 4-3, in overtime. "This type of behavior will not be tolerated in the NJCAA", said Mark Krug, the NJCAA assistant executive director. Erie won in 2015.
