Luke Knox, 22, a Florida International University (FIU) linebacker and younger brother of Buffalo Bills tight end Dawson Knox, died on Wednesday.

FIU coach Mike MacIntyre, who was defensive coordinator at Ole Miss during Luke’s time on the team and is in his first season at FIU, announced Luke’s death today:

Words cannot express the heartfelt sorrow we feel because of the passing of our teammate and friend, Luke Knox. … I had the honor of coaching Luke at Ole Miss and at FIU. While I admired his passion for football, his genuine love for his family and teammates is what I will always remember. He had a special way of making everyone around him feel comfortable and confident. Luke’s family is special to me and they will continually be in my heart and my prayers during this difficult time. On behalf of the entire FIU football family, I extend sincere condolences to Luke’s family and all who love him.
