IOWA CITY, Iowa (AP) – Whatever Iowa coach Kirk Ferentz and his coaching staff have been saying to the Hawkeyes about keeping out of trouble isn’t getting through.

Five Iowa players have been arrested since July, on charges ranging from unauthorized credit card use to drunk driving. The latest dustup came last Saturday night, just hours after Iowa lost to Iowa State, when safety Lance Tillison was arrested for drunken driving.

Ferentz told reporters Tuesday that he has extended the players’ curfews to Saturday. It had been the only night they were allowed to come and go as they pleased.

“I must be a poor communicator. That’s a conclusion I shared with our football team,” Ferentz said. “It’s very disappointing on a couple fronts, if you look at the big picture, the things that have gone on the past … amount of weeks.”

Tillison, a backup safety, has been suspended for this week’s game at No. 9 Wisconsin and the Big Ten home opener against Indiana on Sept. 29. He is the third Iowa player to be arrested on alcohol-related charges.

Cornerback Bradley Fletcher was arrested for drunk driving on July 17 and suspended for the season opener. Long snapper Clint Huntrods was booted off the team after police arrested him in early September and charged him with urinating in public, public intoxication and interference with official acts.

Tillison’s arrest has clearly irked Ferentz, whose team has enough on its plate. After starting 2-0, the Hawkeyes came out flat against Iowa State and now have to travel to Madison to face the Badgers, a favorite to win the Big Ten.

“The unfortunate part there is that Lance is an outstanding young guy. He made a very dumb decision,” Ferentz said. “We got a lot of outstanding guys on the football team. But the facts are the facts. It’s just a poor reflection on our whole football team.”

Douglas and Bowman remain suspended from the team indefinitely after they were arrested Aug. 19 on charges of unauthorized use of a credit card. Ferentz has said that no decision on their status will be made until the legal process runs its course.

Without Douglas, the team’s leading receiver in 2006, Iowa is last among Big Ten teams in passing offense.
