England midfielder Ruben Loftus-Cheek was carried off on a stretcher with a head injury during AC Milan’s 1-0 defeat by Parma.
He collided with Parma goalkeeper Edoardo Corvi when challenging for a cross early in the Serie A game at the San Siro on Sunday.
Loftus-Cheek’s head and neck were put in a brace before he was taken off.
Sky Italia reported that he broke his jaw and several teeth.
A significant injury could affect Loftus-Cheek’s chances of making England’s squad for the World Cup, which starts in June.
