DES MOINES, Iowa — The son of Iowa football coach Kirk Ferentz and two other football players have been charged with public intoxication after an early morning incident Monday.

Coach Ferentz said the players will be suspended from spring practice and must perform community service. Their return to the team will be based on additional criteria, he said.

"It was very disappointing to learn of the behavior of our three players last night," Ferentz said in a statement.

According to a University of Iowa Department of Public Safety complaint, James Ferentz, Zachary Derby and Tyler Christensen, all 19 years old, were arrested at about 2 a.m.

Derby, a redshirt freshman tight end from Iowa City, and Christensen, a redshirt freshman fullback from Belmond, according to a campus police report, tried to pick a fight with an off-duty University of Iowa police officer in the Old Capitol Parking Ramp.

The officer, who wasn't identified, called for backup.

During the incident, Ferentz, a redshirt freshman offensive lineman, came out of the parking lot yelling and stumbling, according to campus police.

Officers suspected the three had been drinking.

Christensen refused a breath test. Derby gave two tests that registered his blood-alcohol content at 0.207 and 0.211 and Ferentz blew a 0.160. The legal limit for driving in Iowa is 0.08.

They were taken to the Johnson County Jail.

Ferentz was also arrested in October for possession of alcohol under the legal age. He later pleaded guilty and paid a fine.

According to the Johnson County clerk's office, Ferentz and Derby pleaded not guilty and are scheduled to appear in court for a bench trial on May 8.

Christensen pleaded guilty to public intoxication and to a charge of criminal mischief and was ordered to pay $100 fines plus court costs on both counts. Searls said Christensen admitted to breaking off a parking arm in the ramp, prompting the criminal mischief charge.
