FILE - Iowa place kicker Keith Duncan (3) kicks a 37-yard field goal during the second half of an NCAA college football game against Nebraska in Iowa City, Iowa, in this Friday, Nov. 27, 2020, file photo. Duncan's wild ride of a career is winding down. He was the Hawkeyes' starting kicker as a freshman, didn’t kick in a game the next two years and then became a consensus All-American with a record-setting season in 2019. He in all likelihood will make his final appearance at Kinnick Stadium on Saturday when No. 25 Wisconsin visits the 19th-ranked Hawkeyes. (AP Photo/Charlie Neibergall, File)
