Buffalo Bills tight end Dawson Knox Mark Konezny-USA TODAY Sports

Florida International University linebacker Luke Knox, the brother of Buffalo Bills tight end Dawson Knox, died suddenly at the age of 22, the school announced Thursday.

In a statement, FIU revealed the “sudden passing” of Knox, but issued no further details.

Bills coach Sean McDermott opened his press conference by offering his condolences to the Knox family.

Luke Knox originally committed to Ole Miss and played there for four seasons. He played in every game for the Rebels in 2019, but after seeing his role reduced, he transferred to FIU ahead of the 2022 season, where he would have been a redshirt senior.

In total, Knox collected 11 tackles, two tackles for loss, and a fumble recovery during his college career.
