Real Madrid are likely to be without Spain international right back Dani Carvajal for the remainder of the season, after he injured his cruciate knee ligament during Saturday night's 2-0 win at home to Villarreal.The defender had to be carried off the pitch in clear pain after a collision with Villarreal's Yeremy Pino in injury time and later posted on social media in the early hours of Sunday morning that: "serious cruciate ligament injury confirmed, I'm going to have to go through surgery and be off the field for a few months.""Already looking forward to starting recovery and coming back like a beast," added the 32-year-old.Real Madrid coach Carlo Ancelotti had previously admitted that he was "worried" for Carvajal in his side's seventh game inside four weeks."Something happened that happens a lot, because of the calendar, and it happened to a very, very important player for us," added the coach.Carvajal's injury leaves Real Madrid with only Lucas Vazquez as their only right back specialist in th e first team squad.The defender had been included in Luis de la Fuente's Spain squad for forthcoming games against Denmark and Serbia, while De la Fuente will presumably now look for a replacement.Ancelotti also explained that Vinicius Jr, who scored Real Madrid's second goal in the win has also damaged his neck and is a doubt for the upcoming international break with Brazil.Source: The Namibia News Agency
