Ex-Indianapolis Colts fullback Roosevelt Potts was sentenced to 2 years in prison for a domestic violence incident in which he slashed a woman with a knife ... but he likely won't spend another minute behind bars.
The story is pretty crazy ...46-year-old Potts -- a pretty solid player back in the '90s -- was found guilty of domestic battery by means of a deadly weapon over a 2016 incident at his Indiana home.
Officials say the victim had two stab wounds on her shoulder following an altercation with Potts.
The woman told police she had grabbed a knife to slash Roosevelt's tires -- when he grabbed a knife of his own and cut her up.
