On Saturday, former world champion Anthony Joshua stopped substitute opponent Robert Helenius in the seventh round of their heavyweight bout.
Helenius was only called up after competing in Finland last weekend, when Dillian Whyte was disqualified from an all-British bout due to “adverse analytical findings” in a doping test.
In October, Deontay Wilder knocked out the 39-year-old Helenius, who entered the ring with a record of 32 victories and four losses in 36 professional fights.
A capacity audience at London’s O2 Arena booed Joshua during the third round as he began cautiously, despite the fact that he avoided a repeat of that humiliating loss on Saturday.
Joshua landed a left hand and then a right to the face later in the round against Helenius.
In the fourth round, the hometown hero once again floored Helenius before the Finnish veteran caught Joshua with a punch.
Helenius suffered a bloody nose in the fifth round, and although Joshua knocked him down with a left uppercut in the sixth, he survived and completed the round without incident.
Joshua did deliver for his supporters when, in the seventh round, he knocked out Helenius with a powerful right-hand punch.
