Sapp cut a huge deal to keep him out of jail in the hooker case -- officials would drop the charges when he finished counseling. But if he got in trouble before he completed the classes, all bets were off.
Fast forward to April 2015, the domestic violence incident. He got 6 months probation in that case ... while prosecutors in AZ argued that the incident violated the terms of their deal.
In fact, AZ prosecutors begged the judge to throw Sapp in jail! But the NFL star dodged a bullet (proving he completed the classes right before the Vegas arrest) ... and the charges were dropped.
Now, we've learned his Vegas probation is over ... so, for all intents and purposes, Sapp has a clean slate.
