Florida International football player Luke Knox has died at 22, the school announced Thursday.
Knox, a native of Brentwood, Tennessee, and the younger brother of Buffalo Bills tight end Dawson Knox, spent the past four seasons at Ole Miss before transferring to FIU.
Knox, who studied business, died Wednesday evening, school officials said. The cause was not revealed, though the university said police do not suspect foul play.
"Words cannot express the heartfelt sorrow we feel because of the passing of our teammate and friend, Luke Knox," FIU coach Mike MacIntyre said in a statement.
