It's an unbelievable story -- Lozito was brutally attacked and stabbed in a NYC subway train on Saturday by Maksim Gelman -- who had been targeted in a massive manhunt after allegedly murdering four people and injuring five during a 28-hour stabbing spree.
But after being stabbed in his head and his arm --Lozito managed to drop Maksim with a single leg takedown ... a move he learned from 20 years of watching the UFC.
Cops swooped in moments later and took Maksim into custody.
Lozito doesn't believe he's a hero. We beg to differ.
