There were concerns for the 18 year-old debutant when he was floored with a head injury attempting to tackle Virimi Vakatawa.

Ezeala's head took the full impact of Vakatawa, running at full tilt, and he was knocked out during his side's 58-6 victory.

The teenager was treated on the field while officials held a white sheet up so he was out of view before he was carried off on a stretcher.

Clermont confirmed later in the day that he had regained consciousness before posting a picture on its Twitter page with the player giving a thumbs up in Beaujon Hospital, where he will be kept in under surveillance on Tuesday and should be discharged by midweek.
