A New Doping Case Hits the ATP Tour

This Wednesday, the International Tennis Integrity Agency announced a one-month suspension for Portuguese player Frederico Ferreira Silva, currently ranked 234th in the world.

In its statement, the ITIA declared: "The International Tennis Integrity Agency (ITIA) confirms today that Frederico Ferreira Silva, a 30-year-old Portuguese tennis player, has accepted a one-month suspension under tennis’s anti-doping program, after testing positive for the banned substance trimetazidine (TMZ) during an in-competition test in February 2025.

The ITIA acknowledged that the positive test was due to contamination from a regulated prescription medication and that the violation was therefore unintentional.

Results for non-specified substances lead to a mandatory provisional suspension – which took effect on March 19, 2025. [...] Since Silva served a period of ineligibility longer than that required by the provisional suspension during investigations and testing, the player is free to compete."

Ferreira Silva had not played between March 2 and June 17 and has therefore already served his suspension.
