IOWA CITY -- Iowa football players have been picking up the tempo out of necessity.

New offensive coordinator Greg Davis said today the Hawkeyes have spent more time in up-tempo and no-huddle offensive looks than they have in recent seasons, something he expects to use at times during the 2012 season.

"The one thing defensive coordinators will tell you is that if you no-huddle all the time, their guys will adjust to the pace," Davis said. "What we like to do is mix it up a bit, change tempos and keep the pressure on the defense."

Davis echoed sentiments expressed by Iowa quarterback James Vandenberg on Tuesday, saying he has been impressed with the skill and development of Iowa's tight ends.

Davis said he has been pleased with what he has seen from the running backs as well.

Iowa will be without one of its projected starting receivers when it hosts a noon public practice Saturday at Kinnick Stadium.

Keenan Davis will miss practices this week with what was labeled a "minor" injury. Davis declined to provide additional details.

Iowa's Shane DiBona will miss the workout as well, also because of an injury. Defensive coordinator Phil Parker declined to say if the setback was related to the Achilles injury which kept DiBona off the field last season.
