Zverev frustrated over Roland Garros insulin ban

German star told not to inject medication during changeovers

"This is a very personal thing": World No. 3 speaks out about diabetes

Alexander Zverev has expressed his frustration at the seemingly unclear rules at the French Open around injecting insulin on court.

The German star was told by match officials that his insulin injections for his type 1 diabetes would have to be done in the locker room, rather than on court, which he called "weird" and "unnecessary".

"I'm not going to go to the locker room to inject my insulin," Zverev said. "It's my body, it's my insulin, and I need to inject it when I need to inject it. I don't think it's fair that they're telling me I can't do that."

Zverev, who has been open about his diabetes diagnosis since being diagnosed with the disease at age three, said he was "disappointed" with the decision. He added that he plans to speak to tournament officials about the matter.

"I think it's important to raise awareness about diabetes and to show people that it's not something that should be hidden," Zverev said.

"I'm a professional athlete, and I'm not going to let my diabetes stop me from achieving my goals. I hope that my story can inspire other kids with diabetes to live their lives to the fullest."
