Serena Williams’ name popping up in the ITIA anti-doping pool has set the tennis world buzzing! Even though the Queen herself says she’s not returning, Danielle Collins and Lindsay Davenport aren’t buying it. Both pointed out on Tennis Channel that you don’t re-enter the testing pool unless you’re serious about a comeback. Collins even threw out a doubles invite! Is Serena really done, or is a legendary return brewing? #Sports #Tennis #SerenaWilliams
