Rafael Nadal says he underwent a surprise doping test toward the end of a week in which the Spaniard was at the center of jokes made by a French TV program about his country's alleged ties to doping.

Nadal wrote on his Twitter account yesterday: "8:30 in the morning!!! Just finished passing a surprise antidoping test ... it was expected after everything ... but I'm happy it's like this!"

The Spanish sports ministry has contacted its French counterparts to complain over the satirical skits, and is considering legal action after Spain's tennis and cycling federations said they would sue Canal Plus for using its logo in a video that poked fun at Nadal. Former Tour de France champion Alberto Contador of Spain received a doping ban last Monday.
