Karim Benzema fractured his finger in Real Madrid's win at Real Betis, coach Santiago Solari has confirmed.
Benzema suffered the injury during Sunday's 2-1 victory at the Benito Villamarin, which was sealed by a late Dani Ceballos free-kick.
Striker Benzema fell heavily on his right hand and was in obvious pain as he left the field shortly before the half-time interval.
Benzema did not return to the pitch for the second half with Solari sending on Cristo Gonzalez for his LaLiga debut.
Solari confirmed Benzema fractured his finger in a post-match interview but gave no expected timescale for his recovery.
