TMZ Sports has obtained footage from the night Buffalo Bills rookie running back Jonathan Williams was arrested for drunk driving … and at one point he begs the officer for mercy because he just got drafted.
Williams — who was selected in the 5th round of the 2016 Draft — was pulled over on July 14th in Arkansas.
The cop clearly suspects Williams is drunk and gives him various field sobriety tests including “walk the line” — Williams bombed that.
Despite the fact he copped to drinking a 40 ounce before getting behind the wheel, Williams refused a breathalyzer and was placed under arrest.
Once in the backseat of the cop car, a desperate Williams tries to explain his situation — saying he was with a woman who was WAY more drunk than he was … and he tried to do the noble thing by driving so she wouldn’t have to.
Williams tells the cop he doesn’t want the officer to jeopardize his integrity — but then drops the whole, “I just got drafted'” line … and says, “I’m really not trying to be in any type of trouble.”
Williams was booked for DWI — he’s due back in court in August.
