Andy Reid has admitted Kadarius Toney did not check with the officials whether or not he was offside before the controversial play that saw the Bills beat the Chiefs on Sunday.
Toney thought he had given the Chiefs a potentially decisive lead in the fourth quarter at Arrowhead Stadium but his touchdown was brought back for a penalty.
The flag led to furious scenes among the Chiefs on the sideline with quarterback Patrick Mahomes screaming at officials and throwing his helmet.
But referee Carl Cheffers said Toney was so far offside that he was ‘blocking our view of the ball’ and admitted he would have given the Chiefs advice on their positioning if they had asked for it.
However, Reid has now confirmed that his players didn’t.
Speaking on Monday, Reid said: ‘Normally he (Toney) just looks over to the sideline and gets an okay and on that one he just happened not to.
‘So that would be the coaching point. Just make sure you check with the guy on the side just to see if you’re aligned.
‘He’s not lining offsides on purpose. Listen, he was two inches or an inch away from being legal.
‘You can argue both sides of it for both teams. I guess the league is trying to clean that up.’
After the game on Sunday, Cheffers said: ‘Yes, ultimately, if they looked for alignment advice, certainly we are going to give it to them.
