Manchester United forward Cristiano Ronaldo has been charged by the Football Association over footage which appeared to show him knocking a phone out of a fan's hand.
Ronaldo, 37, later apologised on social media.
He was cautioned by police regarding the incident in August.
"It is alleged that the forward's conduct after the final whistle was improper and/or violent," the FA said in a statement.
Manchester United said they would support Ronaldo in his response to the charge.
The defeat at Everton dealt a blow to United's hopes of qualifying for the Champions League.
