Former WBA, IBF and WBO Heavyweight champion Anthony Joshua spectacularly knocked out Robert Helenius with one punch in round seven at London's O2 Arena.
The 33-year-old - who was jeered by fans during the fight, landed nothing of note until an overhand right ended Helenius' night.
The win sets up a blockbuster fight with American Deontay Wilder in January.
Joshua extends his record to 26 wins; with 23 stoppages and three defeats.
After the knockout, an emotionally charged yet smiling Joshua climbed out of the ring, high-fived fans and shared a beer with Irish mixed martial arts star Conor McGregor.
The former heavyweight champion was supposed to fight Dillian Whyte, who was pulled from the show after returning an adverse anti-doping finding.
