Ex-NFL wide receiver Dorial Green-Beckham has pled guilty to misdemeanor DWI stemming from a December arrest in Missouri ... TMZ Sports has learned.
The story behind the arrest is crazy ...
The 25-year-old had gotten a call around 3 AM on Dec. 30 from a friend -- who was being arrested for DWI -- and needed Dorial to come pick him up.
When the WR arrived to the scene in his white Cadillac Escalade, cops say they noticed Dorial seemed drunk too and administered field sobriety tests ... which he failed.
