The Football Association has given Manchester City striker Sergio Aguero an extra 24 hours in which to respond to a charge of violent conduct after his apparent elbow on West Ham defender Winston Reid, sources have told ESPN FC.
Aguero faces a three-match ban if found guilty of elbowing Reid in City's victory on Sunday and would miss the Manchester derby at Old Trafford on Sept. 10.
He has now been given until 6 p.m. BST on Thursday to respond to the charge and would automatically receive a three-match ban if he chooses not to contest it.
The incident, which happened in the 76th minute as Aguero challenged Reid from a long clearance, was not punished by referee Andre Marriner, who said in his match report that he had not seen it.
A three game ban would mean Aguero sitting out the Premier League clash with Bournemouth at the Etihad Stadium on Sept. 17 and the EFL Cup third-round clash with Swansea City in addition to the derby.
However, he would be eligible for the Champions League clash with Borussia Monchengladbach, which follows the game against United.
Aguero picked up a calf injury in the victory over West Ham and was substituted in the 88th minute. He has since withdrawn from Argentina's World Cup qualifiers against Uruguay and Venezuela.
