The Royal Spanish Football Federation confirmed the decision on Sunday, stating that the move was taken as a precaution. The statement noted that the player was released to prevent any risk to his health and that Arsenal’s medical team had been fully informed.
Zubimendi had come on as a substitute in Spain’s 3-0 victory over Serbia on Friday, but he will now miss the upcoming friendly against Egypt in Barcelona on Tuesday.
The 27-year-old has made 44 appearances across all competitions this season and has been a key figure in Arsenal’s midfield as they push in the Premier League title race.
His withdrawal adds to a long list of injury setbacks for manager Mikel Arteta, with several first-team players also unavailable during the break. Those affected include Eberechi Eze, Gabriel Magalhães, Leandro Trossard, William Saliba, Jurrien Timber, Bukayo Saka, Declan Rice, Noni Madueke, and Piero Hincapié.
Spain decided to send Zubimendi back early so he can begin treatment in London, where Arsenal’s medical team will evaluate his condition at their training ground. The club remains hopeful that the issue is not serious as they prepare for the return of league action.
