TMZ has learned Vinnie Jones has been charged with three counts of simple assault for that bloody bar fight in South Dakota last week.
Jones was charged for punching the hell out of Juan Barrera in a hallway AFTER the actor was smashed in the face with a glass beer mug. The fight with Barrera was captured on tape by the bar's security camera.
As for Jesse Bickett, the guy who smashed the glass into Vinnie's face, officials let him off the hook -- chalking that rumble up to "mutual combat."
If convicted of all charges, Vinnie could face up to one year in jail and up to $2,000 in fines.
