Kylian Mbappé was sidelined from Real Madrid's Club World Cup match due to his hospitalization for acute gastroenteritis, and the superstar's return date uncertain.

Real Madrid star Kylian Mbappé has been hospitalized “to treat an acute case of gastroenteritis,” the club announced Thursday.

Mbappe’s hospitalisation came almost exactly one year after he sustained a broken nose at the European Championship and had to wear a face mask to continue playing.
