Rapper Boonk Recovers from Broken Jaw Surgery After Getting Punched

Rapper John Gabbana -- aka Boonk -- is on the mend after getting socked in the face, which left him with a busted jaw ... and some gnarly aftermath footage.

Just a warning ... some of these clips are very graphic (close-up shots of Boonk's broken mouth with teeth missing and whatnot). Boonk recorded himself going into surgery Saturday -- where he seemed to be in relatively good spirits surrounded by pals -- as well as some clips of him from Sunday, when he was apparently recovering from his operation. 

In the video from Saturday, you see Boonk with blood spatter all over his tank top and him holding a tube that he used to suck some of the blood from his mouth. Think a dentist's suction device, only bigger ... and bloodier. That's what we got here.

As for how exactly this happened ... Boonk was sucker punched in the face by a short dude.

It's unclear what led up to the assault, or where this even happened, but the seemingly mild blow left a major impact on Boonk's mug. On Instagram, he wrote ... "Broken jaw on both sides, surgery 7:30am. Pray for me, love you guys !! Gotta show them even when I’m down I’m still happy and oh if anyone ask.. I ran into a wall." 

We've been trying to get a hold of Boonk to get more info on what went down, and whether he's filed a police report or not. Considering the circumstances, he certainly could have.

In the meantime, it looks like he's got some love and affection to help him heal, courtesy of a lovely lady who's laying bedside with him.
