Brazil appeal Silva booking

Brazil have lodged an appeal against captain Thiago Silva's yellow card, shown during Friday’s World Cup quarter-final victory over Colombia in Fortaleza.

Thiago received his second booking of the tournament after blocking Colombia goalkeeper David Ospina, which means he is suspended for the semi-final against Germany in Belo Horizonte on Tuesday.

FIFA's head of media Delia Fischer said: "I can confirm we have received an appeal from the CBF (Brazilian Football Confederation) and this is being analysed."

Brazil's chances of success appear very limited as appeals against yellow cards are not usually successful, only red cards.

Real Madrid recently appealed against the yellow card which ruled Xabi Alonso out of the Champions League final during May but UEFA decided that this appeal was inadmissible.

Should FIFA overturn a yellow card it would be hugely controversial, with many suspecting the governing body were favouring the hosts.

However, the CBF is urging FIFA's disciplinary commission "to annul the yellow card unjustly shown."

The CBF also want football's governing body investigate the challenge by Colombia's Juan Camilo Zuniga whose knee-in-the-back tackle on Neymar left Brazil's leading player with a fractured vertebrae.

FIFA has confirmed it is studying the tackle by Zuniga who has already apologised to Neymar.

Meanwhile, all existing yellow cards are now wiped from the slate for the players at this stage of the tournament, so anyone booked in a semi-final will not risk suspension for the final, with only red cards leading to a ban.
