The husband of country music singer Sara Evans won't spend any time behind bars in his domestic violence case ... TMZ has learned.
The Nashville DA's Office tells us ... Jay Barker, a former Univ. of Alabama quarterback, ended up agreeing to a "best interest plea" in which he pled down from felony aggravated assault with a deadly weapon to misdemeanor reckless endangerment.
As we reported, Jay was arrested back in January for allegedly trying to slam his car into the car in which Sara was riding.
