The Spanish football federation have confirmed after tests that Morata has suffered a grade two hamstring tear.

Manchester United talking points after big win over Crystal Palace
Jose Mourinho says that Manchester United's 4-0 win over Crystal Palace was a bigger scoreline than their performance deserved. The visitors started off the game playing deep in their own half hoping to keep a tight game against the Red Devils.
Morata's injury is a blow but with the worldwide break scheduled, it has come at the best possible time for Chelsea.
The ex-Real hitman withdrew from the Spain squad this week following the injury against City.
Batshuayi has scored vital goals for Chelsea from the substitutes' bench and in cup competitions, but has struggled when relied upon from the start against tough opposition.
US dominating Presidents Cup
On the 15th and final hole of the match, Reed wanted to - we guess - motivate Spieth to hole his approach shot on the short par 4. The two South Africans had won four matches at the 2015 Cup, and provided the lone victory for the Internationals on Thursday.
Initial reports on the former Juventus star suggested that the injury was not a serious one, and that he was in with a good chance of returning for Chelsea's Premier League tie with Crystal Palace on the 14th of October.
Since having arrived at Stamford Bridge from Real Madrid this summer, Morata has set the Premier League alight, racking up 6 goals and 2 assists in his first 7 English top-flight appearances.
Should Morata be ruled out for any length of time, then more questions will be asked over why Chelsea did not sign more forward cover during the summer transfer window.
