Dorial Green-Beckham pled guilty in his weed case Friday ... but he reportedly got off with a slap on the wrist -- with a judge sentencing him to just probation.
Green-Beckham was busted in a wild arrest back on Dec. 19 ... when police executed a search warrant at a Springfield, Miss. home.
Cops say they were staking out the place when Green-Beckham showed up and went inside ... and say when they raided the home, DGB tried to escape by jumping out of a window.
That's when they say they tased the 26-year-old former NFL player, put him in cuffs and found two small bags of weed in his pocket.
