Ken Dorsey is going viral for his coaches box meltdown after the Buffalo-Miami game Sunday.

The Dolphins and Bills had a wild finish. After a late safety, the Bills got the ball back trailing 21-19. with 1:33 remaining. Buffalo was on its own 47-yard line facing 2nd-and-20 with 18 seconds left when QB Josh Allen found former Georgia WR Isaiah McKenzie for a 12-yard completion to the Miami 41-yard line. McKenzie was tackled in-bounds and the Bills were unable to get another snap off.

CBS camera captured the angry reaction from Dorsey, the Bills’ offensive coordinator, in the coaches box.

Dorsey, a former Miami Hurricanes standout quarterback, has been an NFL coach since 2013. This is his 4th season on the Bills’ staff.
