June 19 (UPI) -- Real Madrid striker Kylian Mbappe is undergoing treatment at a hospital for acute gastroenteritis, the La Liga soccer franchise announced Thursday.

Madrid played without their star for a 1-1 draw with the Saudi Pro League's Al-Hilal on Wednesday in Miami Gardens, Fla. They will take on Mexico Liga MX squad Pachuca in another Club World Cup match on Sunday in Charlotte, N.C.

"Our player Kylian Mbappe is suffering from an acute case of gastroenteritis and has been admitted to hospital in order to undergo a series of tests and follow the appropriate course of treatment," Madrid said in a statement.

Mbappe, who scored 43 times last season for Madrid, has not trained in recent days. He participated in his first training session with new madrid coach Xabi Alonso on Friday in Madrid. He then flew Saturday to the United States with his teammates.
