A 35-year-old man has been arrested and charged in connection with the assault of Aberdeen midfielder Funso Ojo during their defeat to Dundee United.
Ojo was shown a second yellow card shortly before half-time in Aberdeen's 1-0 defeat at Tannadice on Saturday following an altercation with a fan who pushed him as he hopped the advertising boards after chasing down a ball that went out of play.
The 30-year-old looked to exchange words with the supporter but there was no physical movement from the footballer.
United have cancelled the season ticket of a fan following their investigation into events on Saturday, while a statement from Police Scotland's North East department read: "After an investigation into an incident during the Dundee United and Aberdeen match in Dundee yesterday, a 35-year-old man has been arrested and charged in connection with the assault of an Aberdeen FC player.
"He has been released on undertaking to appear at Dundee Sheriff Court at a later date."
The laws of the game outline an appeal for Ojo's second yellow can only take place in cases of simulation or mistaken identity, meaning he will be suspended for Sunday's trip to Celtic.
Aberdeen chairman Dave Cormack released a statement welcoming the arrest and charge of the 35-year-old man but also urged "common sense" to prevail in Ojo's second yellow card being rescinded.
It read: "The club are appalled at the events that unfolded yesterday afternoon and are fully supporting Funso who remains shaken by the entire incident.
"Such conduct from any supporter is wholly unacceptable and should not be tolerated in what, for a football player, is their place of work.
"Given the circumstances around the incident, the club remain shocked at the decision to issue Funso with a second caution which led to his dismissal from the field of play.
"As it was Funso who was assaulted we sincerely hope that common sense will prevail and that the authorities will work with us to ensure that this injustice is addressed."
Aberdeen are is also awaiting a formal explanation on the reasoning behind manager Stephen Glass' dismissal.
Ian Harkes' late strike gave the home side victory and saw Tam Courts' team move up to fourth, level on points with Hearts who are third in the Scottish Premiership table.
