Kylian Mbappe was released from the hospital Thursday after being treated for an acute case of gastroenteritis. He trained at the club's hotel Friday.

The summer of soccer is taking a new look this year with the FIFA Club World Cup, which brings the first edition of the expanded competition to the United States for a 32-team tournament featuring teams from around the world competing for a share of the $1 billion prize purse.

Kylian Mbappe is ruled out of Real Madrid's second Club World Cup match, but could return for their final group game against RB Salzburg.
