Boston Bruins star Taylor Hall -- a former league MVP -- was so pissed about being shoved into the boards during a game Tuesday night ... he retaliated by sucker punching the dude who pushed him.
The wild scene all went down late in the second period of the Bs' tilt with the Maple Leafs -- after Ilya Lyubushkin hurled Hall face-first into the wall as the Boston winger was trying to cross the midline.
You can see in footage of the play, Hall clearly thought the shove was unnecessary and dirty -- so he ran up from behind Lyubushkin and socked him in the jaw.
