UEFA on Monday opened a disciplinary probe against AC Milan and its Brazilian goalkeeper Nelson Dida for an incident at the end of last week's 1-0 defeat to Celtic in Glasgow.
UEFA will hold a hearing at its headquarters north of Geneva here on Thursday, a spokesman said.
Dida and his club are faced with the possible charge of bringing the game into disrepute by breaching UEFA's fair-play code.
The probe stems from an incident which took place in added time, shortly after the Scottish side scored its winner when Dida fluffed a save.
A Celtic fan ran across the goal-line, chucked Dida thankfully under the chin, and went on his way with the goalie in initial pursuit.
After a few strides Dida changed his mind and crashed dramatically to the ground, holding the side of his head.
He was given treatment on the field before being stretchered off.
UEFA said Milan was involved in the probe along with its player because of the stretcher incident.
It did not say whether it would have expected the club to refuse a stretcher.
Because of the incident, more time was added to the game - time in which Milan could have theoretically equalised.
According to most pundits, Dida did what he did in the hope of having the result reversed.
Games are usually awarded to teams which are the victims of crowd violence.
However, Milan said immediately after the game that it would not complain to UEFA in a bid to overturn the result.
Club officials have subsequently indicated they were embarrassed by Dida's alleged play-acting.
