Rio Ferdinand will not face disciplinary action from UEFA for sarcastically applauding Turkish referee Cuneyt Cakir at Old Trafford on Tuesday night.
The Manchester United defender confronted Cakir after his decision to send off Nani during the Champions League last-16 match against Real Madrid which United lost 2-1 for a 3-2 aggregate defeat.
After receiving the referee's report however, UEFA will take no action against Ferdinand.
UEFA's disciplinary body will assess whether Nani's red card for a high challenge on Alvaro Arbeloa was worthy of punishment beyond an automatic one-match ban.
United manager Sir Alex Ferguson refused to speak to any media following the match, which breaches the obligations set out in UEFA's Champions League regulations. No United player spoke to the media either, which also contravenes the competition rules.
