Retired tennis ace Andre Agassi left his wife Steffi Graf needing stitches after accidentally hitting her with his racket during a charity match on Sunday. The couple, who wed in 2001, were playing at the US Clay Court Championships finals in Houston, Texas, when the accident occurred.

Graf's lip was cut when Agassi's racket hit her face as they played a game while holding hands. Agassi says, "She's OK. It was an unfortunate accident."
