Serena Williams says she's not retired and the chances of her returning to tennis are "very high"

Serena Williams appeared to announce her plans to retire earlier this year, but the tennis superstar and businesswoman recently revealed she is "not retired." During a talk at the TechCrunch Disrupt conference, Williams said the chance of her returning to the sport are "very high."

At the conference for startup companies, Williams and her business partner, Alison Rapaport Stillman, sat down with TechCrunch Editor-in-Chief Jordan Crook to talk about their investment firm, Serena Ventures. 

Crook started by asking Williams about the U.S. Open she competed in last month – which many assumed would be her last ever.
