Arsenal captain Robin van Persie will face no further action over an incident involving Aston Villa defender Carlos Cuellar during the sides' FA Cup tie.
Villa boss Alex McLeish had called on the Football Association to investigate after he believed Van Persie had caught Cuellar with his elbow.
However, referee Mike Jones witnessed the incident at the time, meaning no retrospective action can be taken.
Villa led 2-0 at the break at Emirates Stadium through a Richard Dunne header and a finish from an acute angle by Darren Bent.
But three goals in seven minutes turned the tie upside down, Van Persie making it 2-1 after Dunne fouled Aaron Ramsey.
Theo Walcott levelled before Van Persie sealed victory with a second penalty after Bent's foul on Laurent Koscielny.
