Al Nasr plan to appeal the Asian Football Confederation (AFC) decision to overturn their Champions League win over El Jaish.
The AFC ordered the quarter-final first leg, which Al Nasr won 3-0 away from home last month, to be forfeited.
The body ruled the club had fielded an ineligible player – Wanderley, who scored a brace – in the encounter.
It said the Indonesian passport to register the Brazilian was "false".
Al Nasr responded with a series of tweets, saying they "deplored" the decision and would appeal.
The club were also ordered to pay a fine of $1,000.
The second leg of the quarter-final is due to be played on Wednesday.
