Jeanty attended Carol City High School, where he was rated the 14th-best player in the nation and sixth-best in Florida by The Miami Herald.
[2] Jeanty played for two seasons at the University of Central Florida, from 2000–2001, logging 9.5 sacks and 137 tackles in 22 games.
Due to an injury to David Pollack, Jeanty was tabbed to start at SLB in his NFL debut on September 10, 2006 at Kansas City.
He also had a key special teams play, as his recovery of muffed punt by Dante Hall at the Chiefs 14-yard line was an early momentum-shifter, leading to a Bengals field goal that tied game 3-3.
On January 9, 2010, Jeanty fractured his left fibula on the opening kickoff of a Wild Card playoff game against the New York Jets, ending his season.
