Iowa's A.J. Derby suspended after arrest

Iowa has emerged from an embarrassing series of off-field incidents that surfaced between 2007-09, but the bye weekend produced a conduct problem involving a fan favorite.

Backup quarterback A.J. Derby was arrested Saturday night and charged with fourth-degree criminal mischief and public intoxication after allegedly punching out a window of a bus as he was exiting it.

Iowa on Monday announced Derby has been suspended for two games. The Hawkeyes visit Penn State this week before hosting Northwestern on Oct. 15.

Coach Kirk Ferentz said in a statement that Derby's suspension stems "as a result of his poor decisions this past weekend."

From The Iowa City Press-Citizen:

The criminal complaint states that Derby, who turned 20 in September, admitted to punching out the window and said that he would pay for it. The criminal complaint states that Derby had red, watery eyes and slurred speech, and that he smelled of ingested alcohol. Derby submitted to a breath test that showed he had a blood-alcohol concentration of .120. Derby was taken to the Johnson County Jail about 11:35 p.m. was released about an hour later.

Derby, a redshirt freshman, has seen limited action in two games this season, completing 3 of 6 passes for 30 yards. He has been listed as the No. 2 quarterback ahead of junior John Wienke, who moves into that role for the next two weeks.
