According to 'AS', Real Madrid have decided to appeal what the referee has written in the referee's match report. The club are hoping the ban will be at least reduced as they think the referee's match report contains incorrect information. Modric also gave his version of events on Twitter.
"In the 56th minute, the player (10) Modric, Luka, was sent off for the following reason: for impacting with his studs on the achilles tendon of the opponent without being able to win the ball," the referee Estrada Fernandez wrote. Now, the new rules will give a red for any challenge on that area whether it is deliberate or not. That is what happened with Modric's challenge on Denis Suarez.
Modric could be given a two match ban. Real Madrid believe that Modric did have a chance of winning the ball, which differs from the referee's version of events.
