Real Madrid Castilla suffered a major promotion setback in defeat to Athletic Bilbao B on Sunday.

The 2-1 reverse saw Castilla tumble out of the promotion places.

Enzo Zidane missed a penalty before being sent off.

The midfielder, the son of Real head coach Zinedine Zidane, fired wide a 14th-minute spot-kick, before his dismissal in stoppage time for two yellow-card offences.

Enzo, 21, is the oldest of Zidane's four sons and scored on his first-team debut in the Copa del Rey in November.
