A police report shows Jackson was arrested on the misdemeanour charge Tuesday. The report says a driver told police that Jackson punched him in the face and head during a dispute over a parking space.
The team said in a two-sentence statement it is aware of the charge against Jackson and will make an "appropriate statement" when it learns more facts.
Jackson played for the University of Maryland before being selected by the Cleveland Browns in the second round of the 2006 NFL draft. He played for the team through the 2013 season. He was signed by the Colts as a free agent in March 2014.
