Sergio Ramos and Xabi Alonso were both dismissed and allegedly deliberately got sent off to wipe slate clean.
Real Madrid could see more red after match reports
Uefa will complete a routine study of match reports before deciding whether to take any action following allegations in the Spanish media that two Real Madrid players deliberately provoked red cards in the Champions League.
"The Uefa disciplinary services are still looking at the match reports so [there is] no decision on possible disciplinary cases yet," Uefa said in a statement yesterday.
Sergio Ramos and Xabi Alonso were both dismissed late in Tuesday's 4-0 win away to Ajax after picking up second yellow cards for time-wasting. They face automatic one-match suspensions in the final group game against Auxerre, which is a dead match for Real who are already assured of first place in Group G and qualification for the last 16.
The red cards mean they will have a clean slate for the next round, assuming Uefa hand them only the mandatory one-match ban.
The Spanish sports daily Marca summed up comment across the country's media, saying: "Real Madrid's great match was overshadowed by the self-inflicted sendings-off which had the aim of not accumulating yellow cards before the last 16."
However, Ramos denied to the same newspaper that his red card was deliberate and Jose Mourinho, the coach, would not discuss the matter after the game.
Two years ago, Uefa fined Lyon players Cris and Juninho €15,000 (Dh75,000) and €10,000 respectively for getting deliberately booked during a Champions League match against Fiorentina.
In Holland, Luis Suarez, the Ajax striker, has accepted a seven-match ban for biting Otman Bakkal, the PSV Eindhoven midfielder, in an Eredivisie match.
Ajax, who unilaterally fined Suarez on Monday and banned him for two matches, said they would not appeal against the Dutch Football Federation's ban. Suarez's domestic suspension will keep him sidelined until February 4 next year.
The referee did not see the incident in injury time of Saturday's 0-0 draw and Suarez was not punished.
After the incident, Bakkal pulled down his shirt to show a red mark on his collarbone.
The incident has drawn comparisons to boxer Mike Tyson biting off part of Evander Holyfield's right ear in a 1997 bout and the top-selling Dutch daily De Telegraaf branded Suarez the "Cannibal of Ajax".
Chris Kirkland, the Wigan Athletic goalkeeper, looks set to join English Championship side Leicester City on loan after losing his place to Ali al Habsi, the Oman international.
The move was first proposed by the Premier League side last weekend but was delayed when Kirkland picked up a virus.
Leicester have also signed Roman Bednar, the West Bromwich Albion striker, on loan until January.
