French referee, Tony Chapron has apologized after he kicked out at Nantes defender Diego Carlos and sending him off for a second yellow after being tripped accidentally.
The Brazilian unintentionally collided with the referee as he was tracking back when Paris Saint-Germain counter-attacked. Carlos was already on a yellow card and after hitting the ground, Chapron kicked out and then issued Carlos with a second yellow card and then followed by a red to send him off.
