Luke Knox, a former FIU football player who played in 23 games at Mississippi before joining the Panthers and was the brother of Buffalo Bills tight end Dawson Knox, died Thursday, the university announced.
Luke Knox died Wednesday evening, according to school authorities. The cause was not disclosed, although the university stated that authorities do not suspect foul play.
Knox, a business student, was 22 years old.
"Words cannot reflect our profound sadness at the loss of our teammate and friend, Luke Knox," FIU coach Mike MacIntyre tweeted on social media. "I had the pleasure of coaching Luke at both Ole Miss and FIU. While I loved his football enthusiasm, it is his true love for his family and colleagues that I will remember."
Knox's death was announced to FIU teammates late Wednesday. The team's practice on Thursday was canceled, and grief counselors were brought in to talk with them and other members of the campus community.
Luke Knox's older brother, Dawson Knox, is in his fourth season with the Bills.
"Our thoughts are with Dawson and his family at this difficult time," Bills coach Sean McDermott said on Thursday. "We're right there with him, standing by him and his family. This is the awful news I awoke to this morning."
Luke Knox, a Brentwood, Tennessee native, mostly played special teams at Ole Miss, where he made 11 tackles in four seasons. He converted to tight end in 2021 but played linebacker for FIU this season.
During Knox's tenure with the Rebels, MacIntyre was the defensive coordinator. MacIntyre is in his first season at Florida International.
"He had a unique ability to make everyone around him feel at ease and confident," MacIntyre added. "Luke's family is precious to me, and they will be in my thoughts and prayers throughout this tough time."
