A judge has sentenced the sons of rock star John Mellencamp after they both pleaded guilty to misdemeanor battery charges stemming from a July 2013 altercation.

The Herald-Times reports 19-year-old Speck Mellencamp was sentenced to four days in jail and 20-year-old Hud Mellencamp must serve 50 hours community service. They entered the pleas Friday after the charges were reduced from felonies. They allegedly punched and kicked a 19-year-old man in Bloomington who they believed had hit Speck Mellencamp.

Both also were sentenced to one year of probation.

Monroe County Chief Deputy Prosecutor Bob Miller said the charges were downgraded because medical records did not substantiate "serious bodily injury" as charged in the felony cases.

The Mellencamps' mother, model Elaine Irwin, attended the hearing, but their father did not.
