AC Milan goalkeeper Dida has been given a two-match ban by UEFA following his dramatic fall during his side's 2-1 defeat against Celtic in Glasgow last week.
Dida went down after a Celtic supporter ran onto the pitch in the final stages of the match and appeared to make light contact with the Brazilian.
A statement posted on the club website said: ‘AC Milan announces that it will appeal to UEFA's appeals committee against the two-game ban imposed on its player Nelson Dida.’
UEFA's disciplinary committee said it had fined Celtic £25,000 - half of which will be suspended for a two-year probationary period - for failing to keep the fan off the pitch.
