The International Tennis Integrity Agency (ITIA) has issued a 10-month doping ban to Australian doubles player Thomas Fancutt.

Fancutt said he “unknowingly violated an anti-doping rule” when taking an intravenous vitamin infusion in December 2024, which also coincided with his career-high world doubles ranking of 107 in the same month.

The limit under doping rules is 100ml in a 12-hour period. The ITIA stated the breach was unintentional.

Fellow Australian Max Purcell’s 18-month ban also followed an IV infusion of vitamins.

“The ITIA sent the player (Fancutt) a notice of a potential anti-doping rule violation (ADRV) on 7 March 2025,” the ITIA said.

“Following a full investigation by the ITIA … Fancutt admitted to the breach, and the ITIA accepted that the breach was not intentional.

“The ITIA considered relevant precedents across all WADC-compliant sports, in addition to the player’s early admission and full co-operation.”

While he’ll be able to play again within 12 months, Fancutt will have to forfeit results and prize money he’s amassed over more than a year.

“To the International tennis community, at the end of my 2024 season, I unknowingly violated an anti-doping rule by receiving a 500ml IV infusion to combat severe fatigue,” Fancutt wrote on social media.

“The contents of the infusion were solely Vitamin B, Vitamin C and magnesium. The IV infusion amount however exceeded 100mls which regardless of its content is prohibited under anti-doping regulations, something I was completely unaware of at the time.

“I have always taken great pride in being a clean athlete, and this situation has been devastating for me. While I am deeply disappointed by the suspension, I remain fully committed to the sport and look forward to returning to competition as soon as this matter is resolved.

“During the time, I am fully cooperating with the ITIA and am incredibly grateful for the support of the PTPA and everyone standing by me. I appreciate your understanding and support, and I can’t wait to be back on tour.”
