This Anthony Joshua story reveals how seriously drug testers take their job

Anthony Joshua has offered some insight into the intensity of drug testers.

The IBF world heavyweight champion, who will defend his title at the 02 in London on Saturday against American challenger Dominic Breazeale, revealed that testers from UK Anti-Doping even accompanied him to Nandos to make sure he complied. "The two testers turned up at the place I was staying in Sheffield and wanted a urine sample there and then," Joshua told Sky Sports. "They can stay there for up to two hours while I 'produce', but I had to explain to them that I also needed to eat following a hard training session."

"I wanted some spicy chicken and asked if I could go to the local restaurant. They said okay as long as they could come along with me."

The 26-year-old said that the testers were determined not to let him out of their sight, and joined him at the restaurant, but didn't order anything for themselves. "I don't know if they were hungry, I never asked them and I wouldn't have paid for it anyway, but I enjoyed my spicy chicken. They wouldn't let me out of their sight until they had a sample and were prepared to follow me to the loo to make sure any sample was mine." However, despite his bizarre lunch with the testers, Joshua says he has no issue with following procedures.

"I don't have a problem providing the testers with what they need. I have been tested twice in recent weeks ahead of my title defence against Breazeale."
