The Bills opened their preseason game against the Broncos on Saturday with a special tribute to Florida International linebacker Luke Knox, who died earlier this week at the age of 22.
Buffalo held a moment of silence for Knox, the younger brother of tight end Dawson Knox, prior to kickoff. CBS play-by-play announcer Andrew Catalon announced that Dawson, who is entering his fourth season with the Bills, was not in attendance at the game and will be away from the team indefinitely.
Dawson expressed his thanks for the support his family has received in a tweet Friday.
