Boxing champ Julio Cesar Chavez Jr. -- son of the legendary Julio Cesar Chavez -- won't be heading to jail after his January DUI arrest ... because he just struck a sweet plea deal with prosecutors.
As we first reported, Chavez was hit with 3 misdemeanor charges following his arrest in L.A. -- two for DUI and one for driving without a valid license.
Chavez pled "no contest" to one count of driving with a blood alcohol level of .08 or higher. The other DUI count was dropped, as was the license charge.
Chavez was sentenced to 3 years probation and ordered to attend 30 AA meetings -- which he already did.
His next court date's December 7th.
