One of the top projected prospects in this year's NFL Draft has been charged with one count of aggravated assault and two counts of assault or assault and battery.
The 22-year-old has been projected as the number two offensive tackle available in the Draft and is widely expected to be chosen in the first round.
He was the only person charged regarding the incident and could face up to 93 days in jail if found guilty, although at last month's NFL combine he denied being part of the altercation.
"I went over the Ohio State incident once before. I wasn't in any fight of any kind," Lewan told reporters last month.
"I was actually breaking something up and some guy said that I slugged him, but that's not who I am off the field, that's not the kind of person I am. It might seem that way because of the way I play football, but that's not the way I am as a person."
Lewan started 48 games at left tackle for Michigan and was named the Big Ten's offensive lineman of the year on two occasions.
