Serena's setback raises questions
The void in women's tennis just got exponentially larger.
The foot injury that has kept Serena Williams from playing for the past eight months appears to be the least of her worries.
Reports surfaced Wednesday morning that Williams underwent emergency treatment Monday in a Los Angeles hospital to remove a blood clot in her lungs. Williams reportedly suffered from a pulmonary embolism last week, and in the wake of that doctors treated her for a hematoma.
