Serena Williams admitted on Tuesday that she feared her storied career was over after a leg injury at last year’s Wimbledon forced her off tour for a year and saw her ranking plummet to 1,204 in the world.

“Did I ever doubt I would return? Absolutely, for sure. I would be dishonest if I said it wasn’t [on her mind] and now my body feels great,” said Williams. The 40-year-old made a winning comeback when she teamed with Ons Jabeur to beat Sara Sorribes Tormo and Marie Bouzkova 2-6, 6-3, 13-11 in the Eastbourne International doubles on Tuesday.
