PARIS (AP) - The International Tennis Federation might copy blood-testing measures used by cycling to weed out drug cheats.
ITF anti-doping manager Stuart Miller told The Associated Press in a telephone interview that the federation is working toward more blood and out-of-competition drug testing on players.
Roger Federer and Andy Murray have called for more out-of-competition and blood testing after Lance Armstrong's fall. Murray said the Armstrong example was "pretty shocking."
Miller said the ITF is "looking very, very carefully" at introducing an athlete biological passport program in tennis.
Cycling and track and field monitor athletes' blood values, looking for telltale indications of doping.
