Ilie Nastase could face censure after apparently making a racist comment about Serena Williams' pregnancy on the eve of Romania's Fed Cup tennis playoff against Great Britain.
At a press conference to preview the tie in Constanta, which starts on Saturday, Romania's captain was heard to say of Williams' baby, due in the autumn: "Let's see what colour it has. Chocolate with milk?"
Williams announced on Wednesday she is expecting her first child with fiance Alexis Ohanian, who is white, and will take time away from the tour.
Nastase was not asked about Williams himself but made the comment, in Romanian and clearly audible, to the other players while Romanian No.1 Simona Halep was answering a question about the 23-time grand slam singles champion.
