Former NFL Most Valuable Player Patrick Mahomes and coach Andy Reid criticized referees after the Buffalo Bills upset the Kansas City Chiefs on Sunday, coming minutes after Mr. Mahomes appeared to be criticizing and going after a referee on the sideline.
The Chiefs quarterback was upset at the officiating crew after an offensive offsides call that wiped out a touchdown when Chiefs tight end Travis Kelce caught a pass from Mr. Mahomes and threw a rare backwards pass to receiver Kadarius Toney, who scored. That touchdown would have given the Chiefs a potential 24–20 lead over the Bills with just over a minute in regulation.
