The mother of Kraft Nabisco champion Stacy Lewis fractured a bone in her left leg when jumping into water near the 18th green as part of a tradition for tournament champions.
Carol Lewis fractured her fibula according to the Desert Sun, which quoted Lewis' agent.
"It's a non-weight bearing bone and she is in a soft cast," said J.S. Kang of Sterling Sports, which represents Stacy Lewis. ""[Carol] is doing fine. She may be on some pain medication, but the win is probably the best medicine."
The agent said Carol Lewis had already returned to her Florida home.
Stacy Lewis captured her first LPGA Tour title at the season's first major championship in Rancho Mirage, Calif., on Sunday.
The winner of the Kraft Nabisco Championship typically jumps into a nearby pond and Lewis was joined by her sister, mother, father and caddie. Amy Alcott began the tradition in 1988.
