Here's one of the most insane hockey brawls EVER ... courtesy of players AND coaches in the Federal Prospects Hockey League.
The Columbus River Dragons were getting blown out 7-3 in the 3rd period of a heated game against the Carolina Thunderbirds in Winston-Salem, N.C. ... when a fight broke out that escalated QUICKLY.
You can see in footage ... the whole thing starts when Thunderbirds coach Andre Niec and River Dragons manager Jerome Bechard challenged each other at center ice.
Shortly after ... players got involved -- and it all eventually led to punches and wrestling matches ALL OVER the ice.
