UEFA is considering whether to take action following last night's incident involving a stray Celtic fan and AC Milan's keeper Dida.

Dida appeared to injure himself as he set off to chase the fan, who had entered the pitch to celebrate the 90th minute winner from Scott McDonald.

Whilst Dida appeared unaffected at first by the alleged contact made by the fan, his dramatic fall to the ground has left many viewers of the incident believing he exaggerated the contact.

Celtic must wait until Friday to see whether referee Markus Merk or UEFA delegate Andreas Akkelides have recorded the incident in their respective match reports.
