Lamar Jackson has declared for the NFL draft.
Jackson won the Heisman Trophy in 2016 and was a finalist this year.
ESPN's Mel Kiper ranks Jackson as the No. 7 draft-eligible quarterback for 2018.
"My time in Louisville has produced some of the best memories of my life," Jackson wrote on Twitter. "I have had the pleasure of being in the presence of some of the best professors, coaches, advisers, training staff, athletes and fans, in the nation. With their help, I have been able to grow not only as a quarterback, but as a teammate, student, and most of all, a man."
