Arsenal midfielder Dani Ceballos has undergone an MRI scan after an injury scare with Spain.
On loan from Real Madrid, Ceballos has been a key player under Unai Emery since his arrival, and his injury will be a serious concern for his boss who has already lost striker Alexandre Lacazette to an ankle problem.
Ceballos's solid form this season earned him a call-up to Robert Moreno's Spain squad as they look to continue their strong start to their Euro 2020 campaign.
AS says Ceballos had to end training early on Tuesday after having muscular pains and underwent the scan the next day.
Although a serious injury has been ruled out, Ceballos will likely miss Spain's Euro 2020 qualifying match against Norway this weekend to rest as a precaution.
