Dec 2 - Serena Williams has re-entered the tennis anti-doping testing pool but the 23-times Grand Slam champion denied on Tuesday that the move had anything to do with her making a return to the sport she dominated for nearly two decades.

The International Tennis Integrity Agency confirmed to Reuters that Williams, who has not competed since the 2022 U.S. Open, was among the list of players in its testing pool, which requires individuals to provide their whereabouts at any given time, every day, and participate in random testing.
