Hawkeye defensive end Adrian Clayborn will likely plead guilty in an assault case filed against him, according to court documents filed Wednesday.

Clayborn, 21, was charged with assault causing bodily injury stemming from an incident in January 2009. Clayborn allegedly assaulted a taxi driver over a dispute during a traffic jam. According to court records, a friend had to restrain Clayborn.

The charge, which is a serious misdemeanor, carries a maximum sentence of one year in prison plus a fine of more than $1,500.

It’s unclear whether he will plead guilty to that charge or to a lesser one.

The St. Louis native has been ordered to attend a dispositional hearing at 1:30 p.m. on March 19 in the Johnson County Courthouse.

Johnson County prosecutor Janet Lyness and Matthew Petrzelka, Clayborn’s attorney, did not return messages seeking comment on Wednesday.

Representatives for the athletics department said they did not have enough information to answer questions about the case.
