KANSAS CITY, Mo. — NFL referees are under heavy fire in Week 5.

Late in the second quarter, a sack by Kansas City Chiefs defensive tackle Chris Jones was flagged for roughing the passer on a seemingly routine strip sack.

Jones landed on top of Las Vegas Raiders quarterback Derek Carr, which was the reason for the foul. Even Monday Night Football commentators Joe Buck and Troy Aikman were appalled at the call.

The drive resulted in a Raider field goal.

Roughing the passer has been a controversial call in Week 5.

Atlanta Falcons defensive tackle Grady Jarrett was given the same flag for tackling Tampa Bay Buccaneers quarterback Tom Brady on a seemingly routine sack.

Jones mentioned that play when he talked to the media in the locker room after the game.

“From the refs point of view, it probably looked like that, initially, and when you look at the replay, it’s a whole different thing,” Jones said. “So, I think now, to evolve, roughing the passer—protecting the quarterback, essentially what we’re doing in this league—we gotta be able to look at roughing the passer’s in the booth.”

Chiefs fans proceeded to boo the referees throughout the rest of the game.
