Akers, who ran for 1,144 yards and 14 touchdowns this season, made the announcement on Twitter on Saturday as the Seminoles began pre-bowl practices.
"These last three years have been incredible, and I am so appreciative that the FSU family welcomed a kid from Mississippi with open arms," Akers wrote on Twitter.
Akers is ranked ninth on ESPN draft insider Mel Kiper's list of running backs for the 2020 draft.
Akers had 231 carries, a career high for one season along with his yardage and touchdown totals. He finishes his Florida State career with 2,875 rushing yards (sixth on the Seminoles' career rushing list) and 27 touchdowns. He also had 69 career receptions for 486 yards and seven touchdowns.
Interim head coach Odell Haggins also said senior quarterback Alex Hornibrook and senior linebacker Dontavious Jackson would not be with the team in preparations for the bowl game and instead are working toward their pro futures.
