Jackson was found guilty earlier this month of simple battery. He will be ordered to pay a $1,000 fine for the incident, which could have sent him to jail for 180 days.
Jackson was arrested in Washington, D.C., in February, 2015 after a confrontation with a pizza delivery driver over a parking space. The driver, Jose Bonilla-Fuentes, alleged that Jackson said he was “going to kill me.”
Jackson has started all 32 games for the Colts since they signed him in 2014. He led the team with 89 tackles last season and also recorded three sacks.
The linebacker can still face a punishment from the NFL for the arrest. The victim of the assault also filed a civil suit against Jackson.
