Atletico Madrid confirm Yannick Ferreira Carrasco injury blow a week before Real Madrid clash

Yannick Ferreira Carrasco has given Atletico Madrid a massive injury concern ahead of the Champions League semi-finals with Real Madrid after suffering a "grade I acromioclavicular joint sprain" during his side 1-0 defeat to Villarreal on Tuesday night (25 April).

Carrasco, 23, has become into a key player for Diego Simeone since the beginning of the current campaign, having made the starting line-up in 37 games.

The Belgian international has scored 14 goals and grabbed five assists in the process, being the club's second top joint scorer alongside Kevin Gameiro and only behind Antoine Griezmann.

However, the pacy winger is a major doubt for the first leg of the Champions League semi-finals against Real Madrid on 2 May after suffering an injury in his shoulder during the 1-0 defeat to Villarreal.

Carrasco only came off from the bench in the second half of to replace Nico Gaitan but was forced off only 15 minutes later following a challenge with Antonio Rukavina.

Atletico Madrid have confirmed the blow on its official website.

"The Belgian was X-rayed and the report provided by the club's medical services indicates that he suffers a grade I acromioclavicular joint sprain," the club have confirmed.

Simeone's side have failed to set a timeframe for his recovery but reports in Spain are suggesting that the Belgium international could be out of action for up to two weeks.

According to those initial suggestions, Carrasco would surely miss the first leg of the Champions League semi-finals to be played at the Real Madrid next week while his participation in the reverse fixture at the Vicente Calderon on 10 May could also be in danger.

Meanwhile, the defeat to Villarreal also meant a blow for Atletico in their hope to end the campaign in the third position of La Liga table as fourth-placed Sevilla could go level on points with them if they beat Celta Vigo on Thursday night.

Simeone thus won't be able to rest his key players in Saturday's clash with Las Palmas, which will come only three days before the hotly-anticipated visit to Real Madrid.
