Gonzalo Oliveira, a Portuguese-born player who represents Venezuela, was provisionally suspended for doping on Wednesday.
The International Tennis Integrity Agency said the 29-year-old Oliveira was tested on Nov. 25 while competing at an ATP Challenger event in Manzanillo, Mexico and the A sample was positive for the banned substance methamphetamine.
The mandatory suspension took effect on Jan. 17, the agency said.
Oliveira has not appealed against the ban. He reached a career-high doubles ranking of 77th in August 2020.
