Status of top two backs concerns Iowa

With highly ranked Penn State coming to Iowa City this week, Iowa has to hope that running backs Akrum Wadley (right leg) and James Butler (right elbow) won’t miss extended time. Wadley and Butler, a Nevada transfer, entered 2017 as the only duo in the country to each rush for more than 1,000 yards last season, but both missed most of the second half Saturday against North Texas.
