Two-time world champion Anthony Joshua knocked out mixed martial arts star Francis Ngannou in just the second round of their heavyweight clash in the early hours of Saturday.
Joshua had his Cameroonian opponent on the canvas in the first round and twice more in the second in a brutal and brief exhibition of punching power.
Ngannou, 37, a former UFC heavyweight champion, was taking part in only his second professional boxing match having lost a split decision to Tyson Fury in October.
