Boxing promoter Eddie Hearn has confirmed Anthony Joshua  has triggered an immediate rematch clause following his defeat by Andy Ruiz Jnr.

Ruiz is set for a £10million payday, which is approximately double the purse he netted for one of the greatest upsets in the sport’s history.

Ruiz, who is the new IBF, WBA and WBO champion, had suggested his native Mexico.

With November or December identified for the rematch, it is possible the fight will take place under the roof at Cardiff’s Principality Stadium.
