21 minutes into Tyrone and Monaghan's All-Ireland quarter-final at Croke Park, Conor Meyler broke out of defence with the ball.
The half-forward laid off the ball and then ran into Monaghan's Kieran Hughes.
Referee Marty Duffy called a halt to play and then dished out a black card to Meyler, indicating that it was for pulling down the Monaghan full-forward.
It was a decision which drew plenty of criticism online.
The black card was invented for a reason.. And it wasn't for that. Bad decision. #Tyrone #Monaghan

Black card for Tyrone's Conor Meyler. But he was on the attack, think it was for seeking the foul?! Still doesn't add up.
