Ex-world number one women's tennis player Monica Seles was stabbed on court during her match against Bulgaria's Magdalena Maleeva on April 30, 1993 in Germany. The then 19-year-old Yugoslav was attacked in the back during a timeout with a nine-inch blade by Gunter Parche, who was obsessed with Seles' rival Steffi Graf. Seles returned to professional tennis after two years.
