Wilder admitted to violating his probation during a plea hearing Thursday and was sentenced to 11 days in jail, with credit for eight already served.
That put his expected release date as Sunday, but by Saturday afternoon the rising sophomore was out of jail and already had taken to Twitter, saying, "It feel good to be known as james wilder jr again instead of a number."
Wilder was in jail after failing a breathalyzer test before a court-mandated work-camp day earlier this month. He had previously been sentenced to probation and work camp after pleading guilty to a misdemeanor charge of resisting arrest in April.
His lawyer, Tim Jansen, said the player had hoped to fight the most recent charge in court, but a trial would have required several more weeks of jail time after Wilder's bond was revoked, potentially jeopardizing his chances of playing football this season.
Wilder still must complete two additional anger management classes -- he's finished three already -- and is to remain on probation until October.
Florida State has not issued an official statement regarding potential punishments for Wilder, but because the charge was only classified as a misdemeanor, coach Jimbo Fisher is not required to issue a suspension. Jansen said he has remained in close contact with Fisher throughout the past two weeks and said he was led to believe Fisher was unlikely to hand down any harsh punishment.
