Jackson tweeted Wednesday morning that he will forgo his final season of eligibility. ESPN's Mel Kiper Jr. rates Jackson as the No. 2 draft-eligible cornerback for 2018.
He earned unanimous consensus All-America honors and was named a Jim Thorpe Award finalist and the Big Ten's defensive back of the year after recording a nation-leading eight interceptions and 18 pass breakups. Jackson led the FBS in passes defended and returned two interceptions for touchdowns during his first season as a starter. He also had a forced fumble and a blocked kick for the Hawkeyes, who finished 8-5.
"Growing up, it has always been my dream to play in the National Football League," Jackson tweeted. "I am excited for this next step and humbled by this great opportunity. I will always bleed Black and Gold."
