Robert Helenius has been banned for two years due to anti-doping rule violations for using a prohibited substance for his bout against Anthony Joshua in August 2023, UK Anti-Doping said Friday.
Former heavyweight world champion Joshua beat stand-in Helenius with a seventh-round, single-punch knockout at the London O2 Arena.
Helenius’ sample from a voluntary drug test the day before the bout tested positive for clomifene, which the Finnish boxer said may have originated from consuming eggs and chicken.
Helenius, now 40, was provisionally suspended, and UKAD said he was unable to provide proof that “the eggs and chicken meat he had consumed in advance of the bout originated from hens that had been administered clomifene.”
“Mr. Helenius was therefore unable to identify the source of clomifene in his sample and therefore unable to reduce the applicable period of ineligibility of two years,” UKAD said.
UKAD said that since Helenius was provisionally suspended on Sept. 18 that he has already served 10 months of his ban, which will expire Sept. 17, 2025.
